Question 47
ECNAT2 marksNeeds review
S_PM(t) and S_FM(t) as defined below, are the phase modulated and the frequency modulated waveforms, respectively, corresponding to the message signal m(t) shown in the figure.
and
where K_p is the phase deviation constant in radians/volt and K_f is the frequency deviation constant in radians/second/volt. If the highest instantaneous frequencies of S_PM(t) and S_FM(t) are same, then the value of the ratio K_p/K_f is ______ seconds.
