In a basic CW transmitter, the output from the oscillator is:
- Aat a submultiple of the operating frequency
- Bless stable than the transmitted signal
- Cat the transmitted signal's frequency
- Dat the transmitted signal's power level
Correct answer: C — at the transmitted signal's frequency. From the official ISED question bank, verified word for word.
Why
In a basic continuous wave transmitter, the oscillator is the heart that creates the radio wave, so its output must match the exact frequency you intend to send out. The full explanation — and one for every question — is in Pro.
