... theory of digital signal processing (DSP) and implementation of the theory by devices embedded in what are known as digital signal processors (DSPs). Of course, the theory of digital signal processing ... called the digital signal. Although there is a difference between the discrete-time signal and digital signal, in the next few chapters we assume that the signals are...
