It is characterized bythe use of digital signals to represent these signals as discrete time,discrete frequency, or other discrete domain signals in the form of a sequenceof numbers or symbols to permit the digital processing of these signals.   Theoretical analyses and derivations aretypically performed on discrete-time signal models, created by the abstractprocess of sampling. Numerical methods require a digital signal, such as thoseproduced by an analog-to-digital converter (ADC). The processed result might bea frequency spectrum or a set of statistics. But often it is another digitalsignal that is converted back to analog form by a digital-to-analog converter(DAC). Even if that whole sequence is more complex than analog processing andhas a discrete value range, the application of computational power to signalprocessing allows for many advantages over analog processing in manyapplications, such as error detection and correction in transmission as well asdata compression.
