Question

What do you understand by the term Cross talk?

(a) generation of closely lying sidebands

(b) a method of increasing bandwidth

(c) a method of decreasing bandwidth by converting DSB-SC signal to SSB-SC

(d) disturbance caused in nearby circuit due to transmitted signal

This question was addressed to me in exam.

I'm obligated to ask this question of Methods of Reducing Distortion in chapter Amplitude Modulation of Analog Communications

Answer 1

Right answer is (d) disturbance caused in nearby circuit due to transmitted signal

The explanation is: Crosstalk is a disturbance caused by the electric or magnetic fields of one telecommunication signal affecting a signal in an adjacent circuit. It is generally caused by undesired coupling. In a telephone circuit, crosstalk can result in the hearing part of a voice conversation from another circuit.
