WebThe term ``aliased sinc function'' refers to the fact that it may be simply obtained by sampling the length-continuous-time rectangular window, which has Fourier transform sinc (given amplitude in the time domain). Sampling at intervals of seconds in the time domain corresponds to aliasing in the frequency domain over the interval Hz, and by direct … WebIn signal processing, sampling is the reduction of a continuous-time signal to a discrete-time signal.
