A Superheterodyne receiver is to tune the range from 1MHz to 3.6MHz, with an IF
of 500kHz. The local oscillator frequency is always higher than the incoming RF
signals.
a. Determine the capacitance tuning ratio of the variable capacitor of the
RF circuit
b. Determine the capacitance tuning ratio of the variable capacitor of the
local oscillator circuit
c. Calculate the frequency of the local oscillator if the receiver is tuned to
3MHZ
d. Calculate the image frequency of 3MHz
e. Calculate the Image Frequency Rejection Ratio (in dB) of the receiver if it
is tuned to 3MHz and the F filter selectivity is 100
