A Phase modulator has a carrier signal of ec = 100cos2pi(735x103)t and phase deviation constant of 0.5 rad/V . The modulating signal is defined by the equation em = 2[cos 2pi(8x103)?][cos 2pi(4x103)t]. Determine: a. the rms voltage of the modulating signal b. the phase deviation of the resulting PM signal at t=17.5ms c. the bandwidth of the modulated signal by Bessel approximation

O d. 16W A Capacitor filter is used at the output across the load in order to minimize the ripple factor of the output voltage. The expressions of the average output voltage VDc and the output AC component VACare given below. If R = 1k2 and the single phase bridge rectifier supplied from a 120V - 50 Hz sinusoidal source, then the capacitor value that will maintain the amount of the output ripples to less than 4% would be equal to: VpC = Vm((4FRC – 1)/4fRC) VAC = Vm/(4/2fRC) Select one: a. 126.2uF O b. 93.39uF Oc. 63.39UF O d. 33.2uF TOSHIBA

Show the downward shift of the output signal with the series capacitor and diode.Clampers or DC restorers are clamp a peak of a waveform to a specific DC level comparedwith a capacitively coupled signal which swings about its average DC level (usually 0V).If the diode is removed from the clamper, it defaults to a simple coupling capacitor– noWhat is the clamp voltage? And, which peak gets clamped? Why is this so? Voltage values: Capasitor value: 1000 pFDC offset: 0 VAmplitude: 5 VFreq: 1 KHz
