**Unformatted text preview: **(2) Determine the peak-phase deviation. (3) Determine the peak-frequency deviation. (4) Is this an FM or a PM signal? Explain. Problem 4. The message signal m t into an FM modulator with a peak frequency deviation H z 2 5 v d f is shown in following figure. Plot the frequency deviation in Hz and the phase-deviation in radians. Problem 5. Sketch FM wave for signal 1 ( ) m t in [Fig. 5-1] and PM wave for 2 ( ) m t in [Fig. 5-2]. The constants are 5 1 0 f k and p k . Carrier frequency is 8 1 0 c f . And then discuss about characteristics of waveform results (How can we distinguish signal with waveform). Fig. 5-1 Fig. 5-2...
