Digital signalprocessing is concerned with the processing of a discrete-time signal, called
the input signal, to develop another discrete-time signal, ... .
Project 1.5 Signal Smoothing
A common example of a digitalsignalprocessing application is the removal of the noise
component 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 with
more desirable properties from one or more given discrete-time signals. The processing
algorithm consists...
