Signal Processing Asked on October 24, 2021
Are there any advantages of undersampling or oversampling in signal processing point of view?
Let me suppose that by Nyquist, you mean that there is some frequency $F_s$ such that there is a existence theorem that says:
if one samples any continuous $s(t)$ at $F_s$ (or above), $F_s$ denoting an extremal frequency or a extremal bandwidth, to get a discrete signal $s[k]$, then one can recover $s(t)$ by some algorithm.
