The power supplied to the antenna transmission line by a transmitter during an RF cycle at the highest crest of the modulation envelope is known as:
- Acarrier power
- Bfull power
- Cpeak-envelope power
- Dmean power
Correct answer: C — peak-envelope power. From the official ISED question bank, verified word for word.
Why
Peak-envelope power describes the highest power level reached during a single radio frequency cycle when the signal is modulated, specifically at the very top of the modulation wave. The full explanation — and one for every question — is in Pro.
