Option 2 : 2 and 3 only

Discrete fourier trans form (DFT) is fourier transform of “sampled signal repeated periodically”.
X(t) is smapled and then peridically repeated, its corresponding spectrum is also sampled.
It is obtained by performing a sampling operation in both time and frequency domains.
