Why discreteness in time / frequency domain dictates periodicity in the other frequency / time domian?
- For example the DTFT is perodic in frequency?
- Why it doesn't contain all the frequencies?
- Why the DTFS contain only finite number of frequencies?
NOTE:
I've read the derivation but sometimes i see it's like a definition or a claim in the case of DTFS.
- How we prove that equation of DTFS ? x[n]=N−1∑k=0akejlωon
