Abstract:
The paper put forward a new generalway to analyze the frequency spectrum of periodic signal based on the Mathematica p rogram. Its theoretical p rincip le is Fourier series method of development. The computing difficulty to analyze the frequency spectrum of the ladder wave is solved by the aid of theMathematica p rogram. The frequency spectrum of the ladder triangularwave is analyzed in thisway. TheMathematica p rogram is recommended to do it. As a result, the frequency spectrum structure of the ladder triangularwave is decided by the number 2k of the ladder in a cycle of triangularwave.
