Transmission with SSB, as compared to conventional AM transmission, results in:
- A 6 dB gain in the transmitter and 3 dB gain in the receiver
- B 6 dB gain in the receiver
- C a greater bandpass requirement in the receiver
- D 3 dB gain in the transmitter
Correct answer: A — 6 dB gain in the transmitter and 3 dB gain in the receiver. From the official ISED question bank, verified word for word.
Why
Single sideband concentrates all power into one voice band, unlike AM which wastes energy on a carrier and a second band. The full explanation — and one for every question — is in Pro.
