Two things have been overlooked with phasing amplitude modulation. One is the importance of pulse modulation; the other is that logic gates can be used for analog signal processing. Both of these ...

Modulation is the process of varying a higher frequency carrier wave to transmit information. Though it is theoretically possible to transmit baseband signals (or information) without modulating it, ...

Download this article in PDF format. We also want to recognize Rick Gentile of MathWorks as a co-author of this article. Modulation identification is an important function for an intelligent receiver.

Pulse-width modulation (PWM) is the best conversion method to use for digitally-controlled variable DC voltage sources requiring high accuracy and resolution. Invented 50 years ago 1,2, the PWM ...

Modulation is fundamental to electronic communications. The modulating signal might be analog in nature (voice or music) or digital bit streams. Most modern communication systems are digital, using ...
