The sampling process is the representation of a continuous time domain signal at discrete and uniform time intervals. The maximum amount of information content, or bandwidth, is determined by the Nyquist sampling theory which states that the maximum bandwidth of a data conversion process is equal to ½ the applied sampling rate. Also the sampling rate has an affect on where signal aliasing occurs in the frequency domain. In general, for a given bandwidth, the higher the sampling rate, the less stringent the filtering needs to be.
