Abstract

The authors investigated the errors due to finite duration sampling of continuous signal and determined that this error can be considerable at the beginning and near the end of the sampling time window. These errors has a tendency to get larger at higher frequencies as they approach the Nyquist frequency (fs/2) for signal near the inside boundaries of the time window
