A superheterodyning FM receiver was originally designed and built to operate in the US only. The FM broadcasting band in the US is from 87.5 MHz to 108 MHz. The intermediate frequency of the receiver is fI = 10.7 MHz. This receiver has a poor RF BPF. (a) Determine the frequency range and the tuning ratio of the receiver LO. Can any FM channel in the US be the image station of another FM channel? Explain in detail. (b) If this receiver is brought to another country whose FM band is between 79.5 MHz and 105.1 MHz, what range of desired channels, if any, in this new country are at risk of being interfered?
