Frequency Spectrum Analysis of Sine Ladder Wave Based on Mathematica Program

Long Shu-ming

Abstract

This paper analyses the frequency spectrum structure of sine ladder wave synthesized by digital model converter in detail.Mathematica program which combines wave shape and frequency spectrum is recommended to do it.As a result,it's spectrum structure is decided by change frequency k of DAC in a sine period.The method and the conclusion are useful in the engineering practice.An error in a published paper is pointed out and corrected.
