Understanding what is amplitude modulation and how it works is fundamental for electronics engineering students and professionals working with radio frequency circuits. This comprehensive guide covers ...

Pulse amplitude modulation builds upon this concept by encoding data across multiple voltage levels. PAM4 uses four levels. A PAM4 signal can appear as one of four voltages during each clock cycle, ...

A look at the simplest FM demodulation technique. It doesn’t give the lowest possible output distortion, it doesn’t reject amplitude distortion effects, but it is simple and can be used at virtually ...

An amplitude-modulated envelope centered on 38 kHz that contains the “difference” information used in the demodulation process; Various additional FM modulated subcarriers with an abundance of uses ...

So to be able to move from one form to the other depends on what is required: amplitude, frequency modulation or both. By using PPM, we can do both phase and amplitude modulation, as demonstrated with ...

This letter proposes a demodulation method using a one-bit comparator for signals processed by multilevel pulse amplitude modulation (PAM). The proposed method is simple and provides an alternative to ...
