Q1: The received signal frequency at any time of a super-heterodyne receiver having IF = 456 kHz is 1 MHz. The corresponding image signal is

A within the medium band

B outside the medium band

C depend upon modulation index

D depends on Modulating frequency

ANS:A - within the medium band

Image signal frequency = Received signal frequency - 2 x Intermediate frequency. = 1 MHz - 2 x 456kHz  1 MHz - 912 kHz  88 kHz which lies in medium bond.
