SAMPLING FREQUENCY DETERMINATION FOR UNDE RSAMPLING OF SMALL BANDWIDTH SIGNALS

The relation between the sampling frequency and the bandwidth of an an alogue signal (to be digitalized) according to the sampling theorem al lows to determine all possible sampling frequencies for understanding for a given signal bandwith. This article describes an opposite way fo r solving this problem. For an assumed sampling frequency f(A) we will in the first place evaluate the suitable frequency bands f1 ...f2. Th is approach facilitates a much easier determination of a sampling freq uency appropriate for undersampling and will be discussed with example s.
