The spectrum as defined by the integral Fourier transform for continuous signals does not exist for discrete signals. However, in Section 2.1 we introduced the notion of quasicontinuous signals which ...
A key algorithm that quietly empowers and simplifies our electronics is the Fourier transform, which turns the graph of a signal varying in time into a graph that describes it in terms of its ...
we notice that such a characterization in the frequency domain depends on the continuous variable ?. This implies that the Fourier transform, as it is, is not suitable for the processing of ...
