Although the analysis of periodic signals gives results which can be of great practical interest, the great majority of signals are not of this type. Firstly, even signals which repeat themsel

By contrast, the value of a random waveform or signal is not specified at every instant of time, nor is it possible to predict

Ernst Kofrányi,Friedrichkarl Jekation, we now turn our attention to the ways in which signal properties are modified by various types of processing. Some of the major reasons for interest in signal processing were outlined in sections 1.3 and 1.4. There it was mentioned that by far the majority of signal processing devices are elect
