The FWHM is important in a radio because if it is too broad a radio will pick up too many stations at the same time. This phenomenon is called cross talk. So to prevent cross talk, the FWHM should be smaller than the difference in frequencies between adjacent stations. In FM radio, adjacent stations have a frequency difference of 0.2MHz. If the inductance of a radio is 613nH, what is the largest R can be so that there is no cross talk? Show your math
