An encoding technique used for digital communication, pulse amplitude modulation (PAM) converts a discrete-time signal into a variable-amplitude continuous-time signal that is suitable for high-speed wired communication systems.

Multiplexing was developed in the early 1870s, but it’s become much more applicable to digital telecommunications in the late 20th century. Today, frequency division multiplexing (FDM), time division multiplexing (TDM), and wavelength division multiplexing (WDM) have become an extremely important asset to telecommunication processes and has greatly improved the way that we transmit and receive independent signals over AM and FM radio, telephone lines, and optical fibers.
