Linear convolution is an important calculation in the Digital Signal Processing course.However,some students always have insufficient understanding of its theory and mechanism.In the case of applying linear convolution to modulation spectrum analysis,it demonstrates the mechanism of linear convolution in the analysis of harmonic signals in modulation spectrum.Compared with the traditional"modulation-frequency-locking-filtering"method,students can understand the physical theory and mechanism of linear convolution and its application in engineering practice.
