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

Electronics and Communication Engineering (ECE) : Communication Systems - Quiz(MCQ)

outside the medium band

within the medium band

depend upon modulation index

depends on Modulating frequency

Correct Answer : Option (B) : within the medium band

Explanation : 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.

Which of the following terms are applicable to troposcatter propagation?

SIOs

Fading

Faradays rotation

Atmospheric storms

Correct Answer : Fading

Explanation : Tropospheric scatter propagation is subject to two types of fading called Rayleigh fading (due to multipath propagation) and fading due to variations in atmospheric conditions along the propagation path.
