The effects of noise modulation on the power spectral density functions of a sinusoidal wave are calculated in closed form. Frequency, phase, and amplitude modulation are considered. Noise processes are modeled using Butterworth filters of various integer orders. Both stationary and nonstationary noise processes are included with Daubechies wavelet filters used for the nonsteady case.
