The idea behind the PWM DAC is quite simple: it’s to filter out all of the harmonic content of the PWM signal and be left with only the DC component of it. ... (90-degree phase shift). In that case, ...

Part 2 addresses coupling factor, signal propagation delay, maximum coupling, and vector analysis. Part 3 covers the derivation of parameters, including S parameters, and conclusions derived from this ...

Timing is everything and generating clocks based off a PWM signal is often useful. The same circuit generates up to eight independent clocks using a shift-register. This circuit transforms a pulse ...

Internally this means conventionally creating I and Q streams from the incoming audio, then an algorithm to generate the phase and amplitude for polar modulation.

Modern Modulation Techniques Jul 1, 2014 9:00 AM, Jeremy Ruck, PE Modern society is definitely more mobile than it was several decades ago. Accompanying the increased mobility is a corresponding ...

Making a software defined radio (SDR) receiver is a relatively straightforward process, given the right radio front end electronics and analogue-to-digital converters. Two separate data streams are… ...
