For single-sideband production in AM SSBSC, three transmitter configurations are typically used: the filter approach, the phase-shift method, and the so-called third method. A bandpass filter circuit is used in the filter method to reject one sideband and transmit the remaining sideband. The modulating signal and carrier are applied directly to one of the modulators in the phase-shift method, then both are moved 90 degrees and applied to the second modulator. The outputs of the two balanced modulators are double-sideband suppressed-carrier signals with the proper phase, so that one of the sidebands is canceled when they are combined in a linear summer. The disadvantage of single-sideband transmission is which of the following statements? Select your answer. Tuning single-sideband receivers is more difficult and precise than tuning DSBSC AM receivers. Because most single-sideband transmissions involve a suppressed carrier, envelope detection cannot be employed unless the carrier is…
