1.	Which among the following can be an input to a transmitter?(a) Voice signal(b) Electric signal(c) Light signal(d) Wave signalThis question was posed to me by my school principal while I was bunking the class.I'm obligated to ask this question of Elements of a Communication System in division Communication Systems of Physics – Class 12
Answer» Right CHOICE is (b) Electric signal The EXPLANATION is: If the output of the information source is a non-electrical signal such as a voice signal, then that’s where the transducer comes into PLAY. The transducer CONVERTS this voice signal into an electric form before GIVING it as an input to the transmitter.
