A discrete time, continuous amplitude signalhas R as its range. A discrete time, discrete amplitude signal has Z as its range. Here, the focus ison discrete time signals. Quantization ... signals. Quantization is the process of approximating any discrete time, continuousamplitude signal into one of a finite set of discrete time, continuous amplitude signals based on aparticular distortion...
