Analog transmission is not particularly efficient. When the signal-to-noise ratio of an analog signal deteriorates due to attenuation, amplifying the signal also amplifies noise. Digital signals are ...

This paper presents the Adaptive Differential Pulse Code Modulation (ADPCM) method of digitally storing and reproducing speech or other waveforms. A detailed explanation of the encoding steps is given ...

Doing more with less in electronics often means improving power density. One of the new areas garnering attention involves applying a variety of advanced modulation techniques, including PWM and space ...

Permutation codes are mathematical constructs that utilise the properties of permutations to encode and protect information, with applications spanning powerline communications, flash memory storage ...
