Cases where the linear canonical transform of a signal has compact support or is band-limited
Cases where the linear canonical transform of a signal has compact support or is band-limited
A signal may have compact support, be band-limited (i.e., its Fourier transform has compact support), or neither ("unbounded"). We determine conditions for the linear canonical transform of a signal having these properties. We examine the significance of these conditions for special cases of the linear canonical transform and consider the …
