engineering recuitment GATE ECE 2023-24 Test Series Communication Systems Angle Modulation Maximum Frequency Deviation
Signal m(t) is shown in the figure. This signal is used once to frequency modulate a carrier of frequency fc and once to phase modulate the same carrier.
If kp = 1 rad/V and kf = 1/2π Hz/V then which of the following statements is/are correct?
1
The maximum instantaneous frequency when the carrier is phase modulated will be \({f_c} + \frac{1}{{2\pi }}\)
2
The maximum instantaneous frequency when the carrier is frequency modulated will be \(\frac{1}{2\pi}\)
3
The maximum instantaneous frequency when the carrier is phase modulated will be \(\frac{1}{{2\pi }}\)
4
The maximum instantaneous frequency when the carrier is frequency modulated will be \({f_c} + \frac{1}{{2\pi }}\)
