Spectrum of a Modulated Sinusoid

This model illustrates calculation and display of the spectrum of a modulated sinusoid with noise:

This model shows a simple periodogram spectral estimate of a modulated sinusoid in noise. The top-level parameters control the carrier frequency, the signal frequency, and the noise level. Notice that the two peaks are centered at the carrier frequency, with their distance from the carrier given by the signal frequency. The sample rate is assumed to be 8kHz.
