Dibits as the name suggests are composed of two bits. Dibits is used to obtain Quadrature phase-shift keying by defining four phase shifts separated by 90 degrees. The four patterns of dibits are: -0...
Pulse Code Modulation is a form of modulation that transforms a waveform into a binary signal so that it can be transmitted through the digital communication networks. Digital signal (binary signal) c...
