What is one advantage of carrier suppression in a double sideband voice transmission?
- A Only half the bandwidth is needed for the same information content
- B Greater modulation percentage is obtainable with lower distortion
- C Simpler equipment can be used to receive a double sideband suppressed carrier signal
- D More of the output power can be put into the sidebands
Correct answer: D — More of the output power can be put into the sidebands. From the official ISED question bank, verified word for word.
Why
In a standard double sideband signal, the carrier wave takes up most of the transmitter's power even though it carries no voice information. The full explanation — and one for every question — is in Pro.
