A first-order PLL is operating with zero frequency and phase error when a step in frequency of magnitude au is applied. The loop pain Kt2x(100). Determine the steady state phase error, in degrees, for Aw=2(150) Select one: 60 Does not lock 45 30 Consider an AM system that operates with an index of 0.76 and consider a message signal m(t) - 100cox (200xt). Assuming that coherent demodulation is used, answer the following questions: 1- Determine the efficiency. Answer = 2. Determine the output SNR in terms of (NW) Anster (N, 3. Determine the detection gain Answer A first-order PLL is operating with zero frequency and phase error when a step in frequency of magnitude 80Hz is applied. Determine the steady-state phase error (in degrees) if the loop gain is K. - 25(120) Answer 24 JI 55.14 Loop does not lock 120.41 48.18 A modulated signal is given by(t) = m(t) cos(2*f.1) + m2(t) sin(2*ft) where the baseband signals mi(t) and ma(t) have the tad sienalin kHz will be
