What is one way to produce a single-sideband phone signal?
Use a balanced modulator followed by a filter✓Correct answer
Use a reactance modulator followed by a mixer
Use a loop modulator followed by a mixer
Use a product detector with a DSB signal
Explanation
The filter method starts with a balanced modulator, which cancels the carrier and leaves both sidebands. A sharp band-pass filter then removes one of them, leaving a single sideband. The alternative is the phasing method, which uses quadrature signals rather than a filter.
