In a Frequency Modulator, the carrier signal, ec=8 sin[27(500k)t] is frequency modulated by em=5cos[2n(1k)t]). The Frequency deviation constant of the modulator is K= - 800 Hz/V. Determine: a. Frequency deviation at t=145µsec b. Frequency deviation at t-360usec c. Maximum frequency deviation d. Modulation index of the FM signal e. Equation of the modulated signal f. Instantaneous frequency of the FM signal at t=283usec g. The percent modulation if the modulated signal is for FM broadcast
