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, ... 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 ... Use sinusoidal signals with different frequencies as the input signals and computethe output signal for each input. How do the output signals depend on the frequencies ofthe input signal? Can...
