Consider a narrow-band FM signal approximately defined by )A.coset-B,sin)sinff) 21, sm27,t)sin a) Determine the envelope of this modulated signal b) What is the ratio of the maximum to the minimum value of this envelope? Plot this ratio versus B, assuming Osps03. c) Determine the average power of the narrow-band FM signal, expressed as a percentage of the average power of the unmodulated carrier wave. Plot this result versus β, assuming 0 β 03.
