An Intro to Multiplexing: Basis of Telecommunications

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.
