1. The purpose of the Lag Compensator is: I. Improve the study state response of the close system. II. Speed up the transit response. III. All the above. IV. None of the above.  2. In the Lead Compensator:  I. Z > P. II. Z < P. III. Z = P. IV. None of the above.

Derive the expression for Zin

At two distinct places, a signal is measured. At the first point, the power is P1, and at the second point, it is P2. The decibel level is zero. This denotes

Q1. An FM transmitter has the block diagram shown in Figure Q1. The audio frequency response is constant over the 20 Hz to 20 kHz audio band. The FM output signal is to have a carrier frequency of 90.7 MHz and a peak deviation of 75 kHz. (a) Find the bandwidth and centre frequency required for the bandpass filter. FM exciter fc = 5.00 MHz Oscillator fo= ? Bandpass filter Figure Q1. x8 Frequency multiplier Class C amplifier FM output

RLC Series AC Circuits• Calculate the impedance, phase angle, resonant frequency, power, power factor, voltage, and/or current in a RLCseries circuit.• Draw the circuit diagram for an RLC series circuit.• Explain the significance of the resonant frequency.
