CML ntros NXDN radio fast-track processor

So i found this short article on the internet and i understand that just posting it like a whole article is not the right thing, I got consent from the original writer and read up ways to curate articles, so this is it…….i thought this was fascinating as it highlights some of the highs and lows that I encountered when i was working within the industry.


CML Microcircuits, a leading innovator and provider of low-power semiconductors for global wireless data and two-way radio communications markets, has released an NXDN processor with embedded Air Interface (AI) Protocol.


The CMX7131/7141 with the NXDN Function Image connects directly to the market-leading CMX994 Direct Conversion Receiver IC. Together, these devices form a formidable chip-set, enabling a fast development cycle for small, highly-integrated, multi-standard capable digital radios that will exhibit a long battery life.


The majority of the NXDN air interface physical layer (layer 1) and data link layer (layer 2) is embedded in the NXDN Function Image, plus a host of advanced features to support the complete radio system and simplify the overall radio design process.


NXDN is an FDMA digital Land Mobile Radio (LMR) open standard and has evolved to become a key narrowband technology in the LMR migration from analogue to digital. NXDN is supported by more than 25 international radio manufacturers and organisations that together form the NXDN Forum.


The new NXDN Function Image adds to the existing suite of CMX7131/7141 function images, now covering dPMR, NXDN, ARIB STD-T98, ARIB STD-T102 and legacy analogue PMR. A radio platform using the CMX7131/7141 can be switched to deliver any of these systems by uploading the appropriate Function Image. This allows radio manufacturers to take advantage of economies-of-scale by adopting a Software Defined Radio (SDR) design route, with one radio design supporting a number of different systems and markets.


The DE9944 FDMA SDR Demonstrator is also available, providing the fastest route from development through to production.


The CMX7131/CMX7141 processors and function images are available now, offering low power 3.3V operation in small VQFN/LQFP packaging.

NuForce gets serious about making great headphones

What would you know, this website About keyword is definitely interesting, i trust you enjoy it


The new NuForce Primo 8 in-ears are supposed to be awfully good. The Audiophiliac tries them on.


NuForce is primarily known as a high-end electronics manufacturer that also makes outstandingaffordable products. I’ve been a fan for years, and while they’ve offered headphones in the past, the new Primo 8 in-ears aim higher. I liked them from the get-go, so I used the Primo 8 for a few weeks as my everyday, walking-around headphones. The more I listened, the more I liked them. That’s really saying something because when I’m not reviewing an in-ear headphone I use my Jerry Harvey JH13($1,099) custom-molded-to-my-ears ‘phones. Hey, I’m a headphone reviewer and a hard-core audiophile, so I use the best stuff.


Anyway, the Primo 8, which runs $499, didn’t leave me missing the JH13.


The Primo 8′s rated 38 ohm impedance and high sensitivity make it easier to drive than most in-ears, so it can play pretty loudly from your phone. I found the Primo 8′s isolation from noise on the New York subway better than I’ve found in most universal-fit in-ear headphones. NuForce claims it has a proprietary cable and crossover network for the Primo 8′s four balanced armature drivers in each earpiece. The cables are user-replaceable, so when they break, and all headphones cables will eventually fail, you can just buy a new cable and be on your way. The Primo 8 comes with a huge assortment of ear tips, so getting a good, tight seal should be easy.


The Primo 8′s sound is neutral and clear — there’s no boosted bass or exaggerated treble; it just sounds right. The clarity is unforced, and that’s a rare commodity nowadays. Take the Cardas EM8513 in-ears ($425) — they have more bass and overall detail, but switching to the Primo 8, the sound is far more natural. It’s also more comfortable to wear for extended periods of time. The Sennheiser IE-800 in-ear headphones are more transparent and open sounding than the Primo 8 or EM8513, but the IE-800 sells for $1,000! Again, the IE-800 succeeds by being even-tempered in its sound; nothing jumps out or annoys — the balance is spot on. Even so, the Primo 8 is more comfortable, and until you compare it with headphones that sell for double the price, the sound is very respectable. The Primo 8 is a true audiophile headphone, and while it’s expensive, you’d have to spend a lot more to get something better.

Here"s a Brief History of Headphones

You’ve probably stumbled upon this looking for information about headset’s, hopefully this will help you answer some of those questions, if not please click on one of the relevant links within the article


During the past century, human ears have enjoyed less freedom than ever before, but more music, thanks to the invention of headphones. In 1910, a Nathaniel Baldwin invented headphones in the kitchen of his Utah home, forever subjecting our ears to the shackles of small speakers.


Aside from allowing you to furtively listen to the latest Carly Rae Jepsen single, headphones enable people to privately and individually interact with media, even when in a noisy room or a crowded subway. Headphones are also crucial tools used for recording music, and producing films, TV and radio programming.


Here is a timeline of how we’ve gone from Baldwin’s “Baldy Phones” to Apple’s earbuds EarPods and “Beats by Dre.”


1910: Nathaniel Baldwin Invents the First Headphones


The legend states that Lt. Comdr. A. J. Hepburn of the U.S. Navy received for prototype for a pair of telephones fashioned into a headset, along with a letter from Nathaniel Baldwin written with purple ink on blue and pink paper. After initially disregarding the message, Hepburn tested the device and found that it worked surprisingly well to transmit sound.


The Navy began to ask for more headphones from Baldwin, who could only accept orders of 10 at a time because he was producing them in his kitchen.


If it’s not evident from his choice of stationery and writing utensil, Baldwin was an interesting fellow. He was a fundamentalist Mormon who studied at Brigham Young Academy (later renamed Brigham Young University), and eventually earned an electrical engineering degree from Stanford.


He returned to BYU as a professor but was fired for speaking out in favor of polygamy, a practice which the Mormon Church renounced in 1890. (Though he endorsed polygamy, he had only one wife.)


Original Koss SP3 Headphones1958: John C. Koss Introduces SP3 Stereophones, Made For Music


Until this point, people used headphones almost exclusively for radio communication.


John Koss was born and raised in Wisconsin. He got married in 1952, at which time he started a business using a cash wedding gift with which him and his bride were supposed to buy a sofa, according to the Wisconsin Historical Society.


While introducing a portable phonograph he wanted to rent to patients in Milwaukee hospitals, he revealed the original Koss SP3 Stereophones. Initially intended to be a sidebar, the headphones proved revolutionary because their sound quality made them optimal for listening to music. The Koss Corporation, located in Milwaukee, is still making headphones today.


1979: Sony Releases ‘Walkman,’ Headphones Go on a Diet


Before portable music players, headphones tended to be big. Baldwin’s original set weighed upwards of a pound.


Koss’ stereophones were circumaural, meaning the earpads would literally engulf your ears. It made sense at the time. “Audiophiles” could listen to the latest Beatles, Pink Floyd and Led Zeppelin albums in the comfort of their homes, and the bulbus design of their headphones helped to block outside noise.


With the help of the Sony “Walkman,” recorded music soon liberated itself from the home stereo, creating a need for more portable headphones. Conveniently, a lightweight set of MDR-3L2 headphones was included with the portable cassette player. As opposed to Koss’ circumaural headphones, Sony’s were supra-aural, meaning the earpads pressed against the ears.


 




 



1989: Dr. Amar Bose Introduces the First Noise-Reducing Headset


On a flight home from Zurich in 1978, Dr. Amar Bose tried an early set of electronic headphones that were newly onboard for passenger entertainment — but he could barely hear anything with the overwhelming cabin noise. He returned to Boston and set up a research program at Bose Corporation (which he founded in 1964), to investigate how ambient noise could be reduced with active noise cancellation. The Noise Reduction Technology Group (NRTG) grew out of that program, and in 1989, the company introduced the first noise-reduction headset, designed for the aviation industry.


2001: Apple iPod Includes Earbuds, Which Now Total 600 Million


The trend towards smaller and more portable headphones eventually led to earbuds and in-earphones, which only differ in the degree to which they wedge into the ear canal.


In 2001, Apple introduced the iPod to the world. The iPod, and later iPhone and iPad, comes with a now-iconic set of basic white earbuds. A decade later, iPod sales have topped 300 million. Begin to do the math, totaling sales of iPods, iPhones and iPads, and you begin to realize there are an astronomical number of Apple earbuds in circulation.


During the announcement of a long-awaited upgrade the company’s stock headset at the iPhone 5 unveiling on Sept. 12, Apple said that it had shipped 600 million sets of the first generation of earbuds — that’s roughly one for every 12 people on the planet. Regardless of your opinion on the quality of the product, those earbuds get around.


2008: Beats by Dr. Dre Hits the Market


Hip hop artist and producer Dr. Dre teamed up with Interscope Chairman Jimmy Iovine to launch Beats by Dr. Dre, helping to solidifying headphones as a fashion statement. The brand has recruited celebrities, including Will.i.am, Justin Bieber, Lady Gaga and Lebron James, to endorse the products. Today, Beats by Dr. Dre has 63% market share in U.S. for headphones priced over $100.


2011: Sennheiser Sells $40,000 Orpheus Headphones, World’s Most Expensive


At an audio show in Seoul, South Korea, the German headphone company Sennheiser unveiled the world’s most expensive headphones. The company released 300 sets of the Orpheus headphones, which were priced at 30,000 Euros, or roughly $41,000 a piece.


If you’re still on the fence about making that big of an investment, try them out with the following video.


2012: Apple Redefines Earbuds with the EarPods


The launch of the iPhone 5 ushered in a new era of headphone design — the EarPod. The periscope-like headphones are designed to direct sound right into the ear, and they hold up pretty well.



Headphones have come a long way in the past 100 years, revolutionizing the way we consume media and the way we communicate. In addition to sets that transmit with extremely high fidelity, other notable advancements include wireless headphones, Bluetooth headsets and headsets that include a microphone which can be connected to telephones or computers.


As portable media consumption continues to rise with smartphones and tablets, the need for headphones will be greater than ever.
