SAN JOSE, CALIF. — IMP Inc. has introduced eight pulse-width modulation (PWM) controller ICs for switch-mode power supply and dc/dc converter manufacturers. IMP's BiCMOS IMP38C4x and IMP38HC4x devices ...

TASBot's newest bit of game-breaking magic relies on the vagaries of the NES' DPCM (differential pulse code modulation) sound channel. This one-bit data stream was used to play extremely basic ...

Sponsored by Texas Instruments: For about 25 cents, you can implement many simple analog and digital functions into applications ranging from pulse-width modulation to a stopwatch. Most engineers ...

How pulse-width modulation (PWM) works with switch-mode converters. How PWM can be used in different power-switching applications. Switch-mode converters employ a power semiconductor switch ...

Pulse Width Modulation is definitely the preferred method of dimming an LED with a microcontroller, but we were interested in hearing about a different method called Binary Code Modulation. BCM doe… ...

The "pulse code" in PCM comes from the telephone company's method of sending a pulse or no pulse down the line. Mu-Law signals typically ride on a single 64 Kbps DS0 channel in a T1 line.

So we're going to convert this PDM audio signal with two levels into a PCM (Pulse Code Modulation) audio signal with a multitude of levels. It used to be that the 65536 levels afforded by a 16-bit ...
