A method of encoding information using a binary code of 0s and 1s from electrical pulses. Because digital signals are made up only of binary streams, less information is needed to transmit a message. Digital encoding therefore increases the capacity of a given radio frequency. Furthermore, only digitised information can be transported through a noisy channel without degradation. Digital technology reproduces sound exactly, and can even philtre out background and electronic "noise." Even if corruption occurs, as long as the one zero patterns are recognizable, the original information content can be perfectly replicated at the receiving end. Most new wireless phones and networks use digital technology.
