1.	Why is no carrier signal transmitted when the amplitude of the modulating signal is 0 in an SSB transmission?(a) Attenuation(b) Undermodulation(c) No sideband is generated(d) All the sideband is suppressedThe question was asked in my homework.Question is taken from Single Sideband Modulation topic in division Amplitude & Frequency Modulation of Avionics
Answer» The CORRECT option is (c) No sideband is generated Best EXPLANATION: In an SSB the carrier SIGNAL is suppressed. Also, only when a modulating signal is present the sideband is PRODUCED. When there is no modulating signal there is no sideband produced and the carrier is also suppressed hence NOTHING is transmitted.
