1.	Block diagram of a receiver is shown in the figure:(a) Identity ‘X’ and ‘Y’. (b) Write their functions.
Answer» (a) Box ‘x’ represents IF stage (intermediate frequency stage) Box ‘y’ represents Amplifier. (b) Function of IF stage - It changes the electromagnetic wave of high frequency to a lower frequency for further detection in detector. Function of amplifier - The detected signal may not be strong enough to be made use of, then amplifier is required. Its function is to enhance the power of the signals upto a required level.
