1.	What is the wave of frequency that occurs at the sum and difference of the carrier and modulating signal is called?(a) Noise signals(b) Sideband(c) Extraband(d) Neutral bandI had been asked this question in class test.My question comes from Sidebands and Frequency Domain in portion Amplitude & Frequency Modulation of Avionics
Answer» Correct choice is (b) Sideband To explain I would say: New signals at different frequencies are formed when an INTELLIGENCE signal is modulated with a carrier. These signals are CALLED SIDEBANDS and USUALLY have the frequency of the sum and the difference of the carrier and the modulating signal.
