The peak power output of a single-sideband transmitter, when being tested by a two-tone generator is:
- A equal to the RF peak output power of any of the tones
- B one-half of the RF peak output power of any of the tones
- C one-quarter of the RF peak output power of any of the tones
- D twice the RF power output of any of the tones
Correct answer: D — twice the RF power output of any of the tones. From the official ISED question bank, verified word for word.
Why
When a two-tone generator tests a single-sideband transmitter, it sends two signals of equal strength. The full explanation — and one for every question — is in Pro.
