A superheterodyne receiver is to operate in the frequency range 550 kHz - 1650 kHz, with the intermediate frequency of 450kHz.
Let denote the required capacitance ratio of the local oscillator and I denote the image frequency (in kHz) of the incomingsignal.
If the receiver is tuned to 700 kHz, then
R = 4.41 J =1600
R = 2.10 J =1150
R = 3.0 J =1600
R = 9.0 J =1150
