(a) Sketch the Nyquist diagram for β = 0.20.
(b) Determine the value of β that produces a phase margin of 80 degrees.
A 15kVA has a turns ratio 1:10. If the voltage applied is 13.8kV and the applied load is 20+j6. Find the current in the secondary winding and the active and reactive power consumed by the load
Figure 5.24 shows a symbol for a 512K × 8-bit memory component with tristate bidirectional data input/output connections. Draw a schematic diagram showing connection of these components to form a 2M × 16-bit memory
Determine the maximum raw instantaneous data rate that can be provided to a single user in EDGE, assuming that a single time slot on a single GSM channel is available.
Assume a receiver is located 10 km from a 50 W transmitter. The carrier frequency is 6 GHz and free space propagation is assumed. Assume the unit gains for the system gains. Find: a) The power at the receiver

Consider a superheterodyne FM receiver designed to receive the frequency band of 1 to 20 MHz with an IF frequency 8 MHz. what is the range of frequencies generated by the local oscillator for this receiver
Design low pass active filter with a cutoff frequency t at 10kHz or more by 30db and have the pass band gain positive that does not deviate from 20db by more than 3db. The pass band frequency needed is 800Hz and below Derive transfer function
A 12 pole, 3 phase alternator is coupled to an engine running at 500r.p.m.- Find the slip and the number of poles of the motor.
Letthe predetection SNR be sufficiently high to ensure that the PLL does not lose lock. Using MATLAB and the histogram routine, plot the estimate of the pdf at the VCO output. Comment on the results.
An amplifier has an open-circuit voltage gain of 100. With a 10-KOhm load connected, the voltage gain is found to be only 80. Find the output resistance of the amplifier.
A 3000-lb automobile is driven down a 5 degree incline at a speed of 50mi/h when the brakes are applied, causing a total braking froce of 1200 lb to the applied automoble. Determine the distance traveled by automobile before it come to a stop.
Two L4 X 3 rolled-steel angles are bolted together and used to support the loading shown. Knowing that the allowable normal stress for the steel used is 24 ksi, determine the minimum angle thickness that can be used.
