Multiple Choice
Which best describes how a varactor diode modulator creates FM?
A) The intelligence signal causes the diode to create phase shift which indirectly creates FM
B) The intelligence signal alters the capacitance of the diode to shift the resonant frequency of a tank circuit.
C) The intelligence signal creates mixing action in the nonlinear varactor diode to create an FM signal.
D) The intelligence signal alters the amount of forward bias of the varactor diode to create an FM signal.
