) An FM signal with a modulation index me is passed through a frequency tripler. The wave in the outpyt of the tripler will have a modulation index of : (a) my3 (b)m, Jm, (d) 9m li) A pre-emphasis circuit provide extra noise immunity by (a) boosting the lower frequencies amplifying the higher audio frequencies (e) preamplifying the whole audio band (d) convert the phase modulation to FM Hi) When the modulating frequency is doubled, the modalation index is halved, and the modulating voltage remains constant, the modulation system is (a) AM (b)PM JefEM (djany one of them iv) Indicate which one of the following is not an advantage of FM over AM (a) Better noise immunity is provided a Lower bandwidth is required (e) The transmitted power is more useful (d) Less modulating power is required v) An FM signal with a modulation index my and a carrier frequency f, is passed through a mixer. The wave in the output of the mixer will have : STA different carrier frequency and the same modulation index (b) A different modulation.index and the same carrier frequency (e) A different modulation indes and a different carrier frequency (d) Non of the above ) An FM signal with a modulation index me is passed through a frequency tripler.
