Give the transfer function of this filter

Find K (the constant) for the magnitude characteristic shown in Fig. P12.31, given t1 = 2, t2 = 5, t3 = 9, and t4 = 11, using the transfer function form

A carrier is phase modulated by a sinusoidal signal. The peak phase deviation is one radian when the peak input amplitude is one volt. Find the ratio of the average power in the carrier to that in all sidebands excluding carrier for each of the following cases , and the bandwidth in each case using carsin’s rule (f(t) is given by volt) • F(t) = cos 2500t • F(t) = 4.5 cos 200πt

Find the theoretical resonant frequency of the circuit shown in Fig. 1 by using the resonance frequency formula. Find the transfer function VL1C1(s)/ V1(s) , where VL1C1(s) is the phasor voltage across L1 and C1, s=jw.

Which of the following is the input-output relation of the system whose frequency response is given?( NEED NEAT HANDWRITTEN SOLUTION ONLY OTHERWISE DOWNVOTE).

Find the transfer function of the circuit below and draw the bade plot indicating the cut off frequencies in radians/sec.

Consider the angle modulated signal: v(t) = 10 cos [2πx108t + 3 cos(2πx103t)] Assume that the signal is PM. Find the bandwidth using Carson’s rule of the PM signal when themessage frequency is (a) doubled, (b) halved, but all else remains constant.

Given this transfer fuction of a low-pass filter. Find the cut frequency (image attached below)

a modulating signal given by v(t)=20v; between -2 and 2s and v(t)=0 for another value multiplies the signal cos 400000pi t, Determine the expression in time and frequency of the DBL-PS signal for a power of 6500W
