Find VSWR of a line having maximum and minimum value equals to 120mV and 40mV respectively?(a) 3(b) 2(c) 1(d) 4I have been asked this question in semester exam.The origin of the question is Problems of AM topic in chapter Amplitude Modulation of Analog Communications

Answer»

Right choice is (a) 3

Easy explanation: The voltage standing wave ratio (VSWR) is defined as the ratio of the maximum to minimum voltage on a loss-less LINE. In this way, the VSWR is measured at a particular point and the voltage MAXIMA and MINIMA do not need to be determined along the length of the line.
