Beat
The signal formed when two signals, such as Light waves, of different frequencies are present simultaneously in a nonlinear device. The Frequency of the beat is equal to the difference in frequency of the two primary signals. Beats also are produced in superheterodyne receivers, where the beat is between the incoming signal and the local oscillator in the receiver.
