Q. Discuss the closed-loop behavior?
Consider an elementary feedback control system, as shown in Figure, with H = 1. The output variable c and the input e to the direct transmission path are related by
(a) Assuming the system to be initially at rest, for e = u(t), find the complete solution for c(t) when the system is operated in open-loop fashion without any feedback.
(b) With the feedback loop connected and with a forcing function of a unit step, i.e., R(s) = 1/s, describe the nature of the dynamic response of the controlled variable by working with the differential equation for the closed-loop system, without obtaining a formal solution for c(t).
(c) By working solely in terms of transfer functions, discuss the closed-loop behavior.

In this case, the armature is connected in series with the field coils. Thus I a = I f = I NB. At starting, the back emf is zero (because the m
Explain the Limiting the Spectrum This low-pass filter is known an anti-aliasing filter. These filters are originated at the input to most applications. Since they are required
Q. An n-channel JFET with A = 300 V, P = 2 V, and I DSS = 10 mA is to be operated in the active mode. Determine i D when v DS = 10 V and v GS =-0.5V.
In use, an appropriate bias voltage is applied between the two bases, with B2 made positive with respect to B1. Because the N-type bar is resistive, a relatively small current will
