Issues and New Results on Bandpass Sampling

Abstract

This study presents issues and new results on bandpass sampling. First, some issues on the relationships between the range of allowable sampling frequencies and the guard bands are highlighted. The root cause of these issues was determined. Second, given a specified sampling frequency tolerance and the guard bands for carrier frequency tolerance, a new and simple formula for determining the maximum integer, which is a key number in determining the allowable range of sampling frequencies, has been derived. Two numerical examples were used to demonstrate the above issues and new results.
