PWM is often used as the process control voltage for DC servomotors, and PPM is employed in optical data communication systems. PAM was originally implemented as analog modulation, where the pulse ...

[brmarcum] takes us back to analog building block basics with his Frequency Modulation and Demodulation tutorial. Frequency Modulation (FM) sounds simple at first, but understanding the ...

QAM Modulator and Demodulator combine two amplitude modulation signals into a single data transfer channel: 1. Technique of modifying any one characteristic (amplitude, frequency, or phase) of a ...
