1.	An oscillator is producing FM waves of frequency 5 kHz with a variation of 15 kHz. What is the modulation index?(a) 1.00(b) 3.00(c) 0.5(d) 5.00The question was asked in a national level competition.My question is from Communication Systems topic in section Communication Systems of Physics – Class 12
Answer» The correct option is (b) 3.00 The BEST explanation: Modulation INDEX = \(\frac {\TRIANGLE f}{f}\) Modulation index = \(\frac {15 kHz}{5 kHz}\) Modulation index = 3.
