Hi, I need some hints suggestion on calculating the spectrum of the a pulse width modulated signal. I have a 100kHz pulse signal. The width of the pulse is modulated by another low frequency sine wave (100Hz) so that the pulse width of 100kHz signal varies from 10% to 90%. I want to compute the magnitude of the average spectrum. The average being taken over the time period of 10ms(i.e. period of 100Hz). Kindly suggest how to proceed with it. Any reference would be great start for me. Thanks. Kristo
