(a) Draw the block diagram for an FM broadcast receiver. It is to have one RF stage and an IF frequency of 10.7 MHz. The local oscillator will operate above the signal frequency. Indicate on the diagram the frequency or frequencies at which each stage operates when the receiver is receiving a station at 94.5 MHz.
(b) What is the image frequency of the receiver described above?
(c) Give two ways in which the image rejection of the receiver could be improved.
