Question :(TCO 3) An AM receiver is tuned to receive a carrier frequency of 960KHz and is using high-side injection. What would be the frequency of the image frequency?Student Answer:50KHz 505KHz 1415KHz 1870KHz Instructor Explanation:For high side injection, the image frequency is given by fIM = fC+ 2(455) KHzfIM = fC+ 2(455) = 960 + 2(455) = 1870 KHz
