C)heterodyning.
D)spectrum modulation.

Question

Quizplus · Accepted Answer

Heterodyning is the process of mixing two signals by a nonlinear process to create new frequencies, which are the sum and difference of the original frequencies. This technique is widely used in radio and signal processing to shift signals from one frequency to another.
