A feedback amplifier has a low-frequency open-loop gain of 4000 and three poles at fP1 = 400 kHz, fP2 = 4 MHz, and fP3 = 40 MHz.
A dominant pole is to be inserted such that the phase margin is 60 degrees. Assuming the original poles remain fixed, determine the dominant pole frequency.
Design the system block diagram and one bit cell of a conditional counter which counts only when input count=1?
A non-inverting amplifier incorporates an op amp having an open-loop gain of 100 and bandwidth of 1 MHz. If the circuit is designed for a closed-loop gain of 16, determine the resulting bandwidth and time constant.

Suppose you have a 2 kW electric heater rated for 220 volt operation, which you intend to operate at a reduced power dissipation of 1kW. Calculate the proper amount of voltage you would need to achieve this reduced power dissipation
Discuss the statement "If you were a historian, what kinds of documents and artifacts would you study and then write about to help people in the future to understand the events of September 11, 2001."
a ladder 61 ft. long is leaning against the side of a house. the base of the ladder is sliding away from the house at a rate of 6 ft/sec. At what rate is the top of the ladder sliding down the house when the base of the ladder is 11 ft. from the h..
a. Functionally, how do closed-loop systems differ from open-loop system b. State one condition under which the error signal of a feedback control system would not be the difference between the input and the output.
a. Convert the per unit generator reactance to the step-up transformer base.
