Indicate which one of the following advantage of the phase cancellation method of obtaining SSB over the filter method is false?
-
- Switching from one sideband to the other is simpler.
- It is possible to generate SSB at any frequency.
- SSB wilth lower audio frequency present can generated.
- There are more balanced modulators, therefore, the carrier is suppressed better.
Correct Option: D
The main advantage of phase cancellation or phase method is that it does not require any sharp cut-off filter. Here each modulator is carefully balanced in order to suppress the carrier, for this each modulator should have equal sensitivity to the baseband signal.
Hence alternative (D) is the most appropriate choice.
