Generate the spectra of the signals at different points in the sampling system. Reals?Complex, The system creates a signal with Dirac delta, To perform the interpolation, the signal is first, For zero-order hold, the LTI system has impulse. () Continuous Signals ... Nyquist in terms of Reconstruction If the sampling rate, , is not large enough (larger than twice the bandlimit, ) then the aliases will overlap: an effect known as Aliasing. Equivalent sampling solves the problem of signal sampling and reconstruction at the sub-Nyquist sampling rate, but this theory has requirements for the sampling process.
