I am currently writing a report for university about DSB (double sideband) modulation techniques and balanced modulators. Here is the question that need to be answered:
The balanced modulator is used for:
- (a) For stabilization between left and right channel while in stereo mode?
- (b) To remove the phase inversion from the signal and therefore this signal can be demodulated by a detector?
- (c) It searches for balance in power between sidebands and carrier?
- (d) Needing 2 identical AM modulators?
It doesn't ask to explain the reason we give a particular answer, but I would like to hear from you an explanation.
