AN-236An Introduction to the Sampling Theorem

The sampling theorem by C E Shannon in 1949 places restrictions on the frequency content of the time function signal f(t) and can be simply stated as follows: — In order to recover the signal function f(t) exactly it is necessary to sample f(t) at a rate greater
