# F.M., A.M. and S.S.B. transmitters

### Explanation of question 14

A double-sideband AM transmitter uses a correctly adjusted balanced modulator. The result will be

1. single sideband, suppressed carrier
2. double sideband, suppressed carrier
3. single sideband, full carrier
4. double sideband, full carrier

The answer is :- 2 Transmission of an a.m. signal is double sideband with carrier. Suppressing the carrier (by a balanced modulator) will therefore leave two sidebands and a suppressed carrier.
