This is because MATLAB provides...
... Signalsin the Time Domain11.1 Introduction Digital signalprocessing is concerned with the processing of a discrete-time signal, calledthe input signal, to develop another discrete-time signal, ... .Project 1.5 Signal SmoothingA common example of a digitalsignalprocessing application is the removal of the noisecomponent from a signal corrupted by additive noise. Let s[n] be the signal corrupted ... indicated earlier, the purpose of digitalsignalprocessing is to generate a signal withmore desirable properties from one or more given discrete-time signals. The processing algorithm consists...
