Fourier Transform of Digital Signals,sential formula for Fourier analysis of periodic signals. We demonstrate the Shannon theorem, which sets the conditions for which sampling takes place without loss of information. We show the Whittaker–Shannon theorem proving that an analog signal can be reconstructed from its samples if the samplin

,Minimum-Phase Systems—Deconvolution, of the frequency gain, that a filter whose zeros are located within the unit circle will have a lower variation of phase with frequency. It follows that the impulse response of this filter is earlier. Since a minimum-phase causal filter has its zeros inside the unit circle, its inverse will be caus

Wavelets; Multiresolution Analysis,f the properties of a signal. Wavelet bases with compact support, which could be used by simple filtering operations, have been searched. These bases must also allow reconstructing the signal accurately and easily from the decomposition coefficients. It is known that the details of a signal are cont

Hossein Mesbahian,Trevor Norris of operation and gives way to generalization toward ARMA filters (Autoregressive–Moving Average) of which several examples are studied. It is interesting to be able to use the many accumulated results in the literature on analog filters; various methods of passing from an analog filter to its digit
