Abstract：Based on the analysis of the spurious spectrum introduced by phase truncation which was made by Nicholas, the new simplified algorithm of spurious spectrum in the presence of phase truncation is presented by using the mapping mathematics and number theory. It is possible to precisely analyze the spurious spectrum location and the spurious amplitude introduced by phase truncation in practical applications.
