1.	Name the process of recovering the original information signal from the modulated wave at the receiver end.(a) Attenuation(b) Demodulation(c) Modulation(d) BandwidthThis question was addressed to me in quiz.The query is from Basic Terminology Used in Electronic Communication Systems topic in portion Communication Systems of Physics – Class 12
Answer» Correct OPTION is (b) Demodulation Explanation: The PROCESS of recovering the original information signal from the modulated wave at the receiver END is called demodulation or detection. It is the reverse process of the modulation process that OCCURS at the TRANSMITTING end.
