Time Aliasing: A Digital Data Processing Phenomenon
R. Joe Thornhill, Craig C. Smith · Journal of Dynamic Systems Measurement and Control · 1983
The frequency sampling theorem is developed and interpreted for a function of frequency which was sampled either directly or indirectly by spectral identification techniques. An example of the results of time aliasing when the frequency resolution is too coarse is presented. A generalized window is developed which implements a zoom inverse discrete Fourier transform for avoiding undesirable time aliasing effects.
