• (A) A frequency modulated signal is produced when a modulating signal m (t) is integrated and applied to a phase modulator
• (B) For a sinus dally modulated FM carrier, it is possible that for particular values of the modulation index ?, all the power in the carrier
• (C) When carrier to noise ratio is high, an increase in the transmission bandwidth decreases the figure of merit of an FM system
• (D) A phase modulated signal is produced when a modulating signal m(t) is differentiated and applied to a frequency modulator
