1. c(t) and m(t) are used to generate an FM signal. If the peak frequency deviation of the generated FM signal is three times the transmission bandwidth of the AM signal, then the coefficient of the term cos [2p (1008 x 103t)] in the FM signal (in terms of the Bessel Coefficients) is

    As, we known FM, s(t) Frequency deviation = 3 . (AM Bandwidth) = 6 fm and β= 6 is given in (d) only. ωc + n ωm = (1008 x 103)2p 2p x 106 + n. 4p x 103 = (1008 x 103).2p n = 4 So, β = 6, n = 4 hence answer is 5j4(6).
