1.	What will be the effect on power if the modulation index of a frequency modulated signal is increased?(a) increases(b) decreases(c) remains constant(d) first increases and then decreasesThis question was posed to me during an online interview.Enquiry is from Carrier Acquistion Techniques in DSB-SC topic in division Double Sideband Suppressed Carrier Modulation of Analog Communications
Answer» Right CHOICE is (c) remains constant To explain I would SAY: In frequency modulation, power remains constant. So if we increase the modulation index then ALSO it does not affect power, it will remain constant.
