In an FM transmitter, the frequency multiplier:
- Aproduces a low distortion audio response
- Bproduces the FM output carrier frequency
- Callows the oscillator to be run at very high frequencies
- Dis the major load fed by the power supply
Correct answer: B — produces the FM output carrier frequency. From the official ISED question bank, verified word for word.
Why
A frequency multiplier takes the signal from a stable, lower-frequency oscillator and increases its frequency to reach the final channel you need to transmit on, effectively creating the FM output carrier frequency. The full explanation — and one for every question — is in Pro.
