A VHF. transmitter, designed to operate on 144MHz, has an 8MHz crystal oscillator and a three-stage frequency multiplier. If the first and second stages are both frequency triplers, the third stage will be to multiply the frequency from
The answer is :- 3 First stage will multiply frequency from 8 MHz to 3 x 8 = 24 MHz. Second stage will multiply frequency from 24 MHz to 3 x 24 =72 MHz. The third stage must multiply the frequency from 72 MHz to 144 MHz, i.e. a frequency doubler.
