this is my last hope on passing the course.. so any help would be greatly appreciated..
1.A superheterodyne receiver having an RF amplifier and an IF of 450 kHz is tuned to 15Mhz. Calculate the Qs of the RF and mixer input tuned circuits, both being the same, if the receiver's image rejection is to be 120
2. WHen a superheterodyne receiver is tuned to 555 kHZ, its local oscillator provides the mixer with an input at 1010 kHZ. What is the image frequency? The antenna of this receiver is connected to the mixer via tuned circuit whose loaded Q is 40. What will be the rejection ratio for the calculated image frequency?
