Re: Sampling Theorem

hello,
The Basic sampling theorem is Nqyist Therem..which states that the sampling frequency of a BandLimited signal(B.W.=B Hz) should be twice of the B.W. sampling frequence=2B Hz....this is minium sampling rate required for reconstructing the signal from it's samples.
If u take sampling frequency fs<2B then there'll overlapping between adjacent intervals of the sample. [/code]
