Draw the block diagram of a superheterodyne AM receiver, briefly explain the function and characteristics of each element in the diagram. Particularly, put emphasis on how a signal at the so- called image frequency is rejected by proper choice of RF amplifier bandwidth, and also elaborate on the frequency response characteristics of IF and RF amplifiers. b. Sketch a block diagram of a superheterodyne FM radio receiver, and what is the bandwidth and center frequency of IF amplifier in this case. Comment on the functions of clements after the IF amplifier. , Consider the case of stereo FM broadcasting. a.
