AM调制 MATLAB编程
Comparing with spectrum of AM modulation, we can observe variety of amplitude and width about modulated signal spectrum which is generated by different modulation coefficient and different carrier frequency. When the modulated signal and its carrier don’t change, Modulation coefficient varies from 0.1 to 1.0.It increase at every 0.1, observing variety of amplitude and width about modulated signal spectrum. The carrier frequency is 50Hz or 150Hz, modulation coefficient and modulation signal are unchanged then we can analysis variety of amplitude and width about modulated signal spectrum. With modulation coefficient increasing, amplitude of modulated signal spectrum is reduced and its width is not change. When carrier frequency is enlarging, width of modulated signal spectrum is widened and amplitude of modulated signal spectrum is not change.
