1.	Noise is added to a signal ________(a) In the channel(b) At receiving antenna(c) At transmitting antenna(d) During regeneration of informationI have been asked this question by my college professor while I was bunking the class.Enquiry is from Channel topic in division Elements of Communication System of Analog Communications
Answer» Correct answer is (a) In the channel For explanation: Noise is an unwanted signal that gets mixed with the TRANSMITTED signal while passing through the channel. The noise interferes with the signal and PROVIDES distortion in received signal. The transmitting antenna transmits modulated message signal while the RECEIVING antenna receives the transmitted signal. REGENERATION of information refers to DEMODULATING the received signal to produce the original message signal.
