In like fashion to switchmode (versus linear) power supplies, which previously made their grand contribution to ultraminiaturization in portable communications devices, the Class D “digital audio” ...

Technology has democratized the music industry in many obvious ways – notice how every band, regardless of stature, has a MySpace page? But one of technology's more subtle effects has been to make our ...

Class D amps are simple – just take an input, and use that to modulate a square wave with PWM. Send this PWM signal to a MOSFET or something, and you have the simplest class D amp in existence.

For driving an antenna, efficient generation of a clean and stable signal is required for optimum performance of many systems. This paper focuses on methodologies to efficiently apply a pure, ...

Class D amps from $130 to $50,000—pulling more ears into hi-fi without demanding you sell a kidney. Solid tech, serious power, and none of the usual overpriced fluff. Finally, affordable doesn’t sound ...

Hang around in any of the many guitar or audiophile forums or discussion boards for long enough, and eventually you’ll come across the arguments over amplifier topologies. One of the more interesting ...

Learn how power amplifiers work, the common types, and what to lookout for when shopping for amps. You have to find out if the amplifier is a Class A/B analog amp or a Class D digital amplifier before ...

HARMAN is one of the largest and highest profile audio manufacturers in the professional and consumer markets, and during the recently completed InfoComm Show the company’s Crown brand debuted several ...

Because pulse modulation output signals are either on or off, Class D amplifiers produce far less heat than analog amplifiers. Reaching efficiencies greater than 90% compared to only 50% for analog, ...

What is class D amplification? Class D amplifiers are a more efficient alternative to class AB (push-pull) power amplifiers for audio signals. Class D is particularly attractive in portable ...

This article was originally published in the Dec 14, 1998 issue of Electronic Design. Class-D audio power amplifiers (APAs) were first introduced nearly 50 years ago. Since then, they have been used ...

After you're done pulling all the wires for whole-home audio, you probably want some peace of mind that the system will just work with no fuss, like, forever. If your setups are of the high-end ...
