Signal m(t) is shown below the signal is once FM modulated and once PM modulated to a carrier of frequency fc. If kp is the phase sensitivity of the PM modulated wave and kf is the frequency sensitivity of the FM modulated wave, which of the following statements is/are true?
1
The maximum instantaneous frequency when the carrier is phase modulated will be \({f_c} + \frac{k_p}{{2\pi }}\)
2
The maximum instantaneous frequency when the carrier is frequency modulated will be fc + kf
3
The relation between kf and kp such that the maximum phase deviation of the modulated signal is the same in both cases is: 2π kf = kp
4
None of the above
