1.	Which of the following is the reason for signal distortion?(a) Speed of the signal(b) Wearing down of the essential elements(c) Absence of a channel(d) Channel imperfectionI have been asked this question in exam.Question is from Elements of a Communication System in chapter Communication Systems of Physics – Class 12
Answer» The CORRECT CHOICE is (d) Channel imperfection For explanation: Channel imperfection is that the reason for distortion when a transmitted signal propagates ALONG the channel. Moreover, the receiver receives a corrupted version of the transmitted signal thanks to the addition of noise to the transmitted signal.
