Question

How multiplier and divider technique can be used in signal generator?​

Answer 1

Explanation:

Frequency multipliers are often used in frequency synthesizers and communications circuits. It can be more economical to develop a lower frequency signal ...

A frequency multiplier can be designed using a PLL and a 'divided by N' counter. The frequency divider is inserted between the VCO and phase detector of PLL circuit. Therefore one input of the phase comparator is the input signal and the other is the output of 'divided by N' counter.
