What is the function of a frequency doubler in a frequency synthesizer?

How does a varactor diode function in frequency modulation circuits?
Answer : A varactor diode is commonly used in frequency modulation (FM) circuits because of its ability to change capacitance when a reverse bias voltage is applied. This change in capacitance can ... circuits, allowing precise control over the oscillator frequency, and thus enabling the modulation process....
