1.	What do you understand by the term “carrier” in modulation?(a) voltage to be transmitted(b) resultant wave(c) voltage for which amplitude, phase or frequency can be varied(d) voltage for which amplitude, phase or frequency remains constantI had been asked this question in class test.I'd like to ask this question from Method of Generation of SSB-SC topic in chapter SSB Modulation of Analog Communications
Answer» The correct choice is (c) voltage for which amplitude, phase or frequency can be varied For explanation I would say: Carrier wave is the wave with frequency HIGHER than the message signal, WHOSE certain CHARACTERISTICS like amplitude, phase or frequency are varied with respect to the instantaneous amplitude of the message signal. THUS forming the modulated wave which is the wave to be transmitted.
