1.	What is the expected modulation index in case of narrow band FM?(a) less than or equal to 1(b) infinite(c) 1.5(d) more than 1I had been asked this question in an online interview.Enquiry is from Comparision of SSB Suppression Techniques in chapter SSB Modulation of Analog Communications
Answer» Correct choice is (a) less than or EQUAL to 1 The explanation: For producing Narrow band frequency MODULATED WAVE, modulation index should be less than or equal to1. For WIDEBAND frequency modulated wave, modulation index should be greater than 1.
