Problem on feedback systemWhat are the techniques used to make feedback system stable?
Explain and draw the frequency response of a 1-pole feedback amplifier.
In a 3-pole feedback amplifier the loop gain is given by:
t(f)=(Beta*100)/ ( (1+j*(f/10^4)) * (1+j*(f/10^5))^2 );
Determine the stability for Beta=.5 and .05. Sketch the Nyquist plot for both cases.
Compute the rectangular form of the four-point DFT of the following signal, which is zero for n =4. Compute the inverse DTFT of: X(ω)=sinΩ cosΩ
A radio receiver for the HF band covers the frequency range 2 MHz to 30 MHz. The first IF frequency is 3.0 MHz and the local oscillator is above the received signal frequency.
Saturated and unsaturated synchronous reactance, The following readings are taken from the results of an open- and a short-circuit test on a 9375-kVA three-phase Y-connected

Calculate capacitor size, An electrical supply company charges its consumers a penalty if their reactive energy consumption (Kvar-hour)exceeds half their true energy consumption (Kilowatt-hour).
The waveform output by the signal generator in part (b) is changed so that the rectangular pulses have the same width but no longer are periodic. They occur at random intervals of time. Explain in words how the display on the spectrum screen would..
Resisitive load, A 4:1 step down transformer uses a 60Vac source on the primary windings.
If we have a 600ohm transmission line terminated with a 1200ohm resistor, how long must the transmission line be if the input impedance is purely real?
