Question
Commercial AM broadcast stations operate between 540KHz to 1600KHz, with a transmission bndwidth limited to 10KHz.

a) Draw a block diagram for an AM heterodyne receiver.

b) If the IF is 455KHz. determine the range of turning that must be provided in the local oscillator when the local oscillator frequency fLo is higher than the carrier frequency fc (super-heterodyning).

c)Repeal part (b) when fLO is lower than fc(sub-heterodyning).

d) Explain why the usual AM radio receiver uses a super-heterodyne system.

e) commercial AM receiver is tuned to a radio station having a carrier frequency of 1120KHz, what is the carrier frequency of the image station?
