3.Calculate the image frequency rejection of a double conversion receiver which has a first IF of 2 MHz and a second IF of 200 kHz, an RF amplifier whose tuned circuit has a Q of 75 (the same as that of the mixer) and which is tuned to a 30 Mhz signal. The answer is to given in decibels.

4. Caculate the image rejection of the receiver having an RF amplifier and an IF of 450 kHz., if the Qs of the relevant coils are 65, at an incoming frequency of
a.) 1200kHz
b.) 20 Mhz
