1.	7. Write the functions of the following in communication systems. () Transducer /if Repeater(it)Modulator
Answer» A transducer is a device that converts energy from one form to another. Usually a transducer converts a signal in one form of energy to a signal in another In telecommunications, arepeateris an electronic device that receives a signal and retransmits it.Repeatersare used to extend transmissions so that the signal can cover longer distances or be received on the other side of an obstruction. In electronics and telecommunications, modulation is the process of varying one or more properties of a periodic waveform, called the carrier signal, with a modulating signal that typically contains information to be transmitted.
