Determine the value of gain, k which would lead to marginal stability. Using MATLAB, plot the step response of the closed loop system with this value of gain.
The substrate concentration of a N-type semiconductor is ND=10^15cm^-3. the wafer is doped with NA= 1.1*10^15 cm^-3, so that a very lightly doped P-type region is created at the surface. What is the concentration of electrons in the P-type region
Note that after a collision, the expected numbers are slightly different in two systems, but the difference is unimportant since collisions are rare.
(a) At t = 0, the current flowing in a 0.5-H inductance is 4 A. What constant voltage must be applied to reduce the current to 0 at t = 0.2 s (b) Starting at t = 0, a constant 12-V voltage source is applied to a 2-H inductor.
In animation programs, special effects are achieved by changing the properties of objects. What instruction is used to change the opacity and color properties of objects in the Zeus example world?
Explanation of the circuit: Two opamps on the top are the buffer amplifiers before and after sampler. Sampler is a JFET used as analog switch; its gate is driven by the narrow pulse train as specified above. There are two identical active lowpass ..
1. Determine Laplace transform of (2-2e^-4t)u(t) 2. Determine if x(t) = 9cos(2t)+4sin(pi t) is periodic; if periodic, calculate the period. 3. Compute the inverse Laplace transform of X(s)= (s+2)/(s^2+ 7s + 12).
Design a 7.5-V zener regulator circuit using a 7.5-V zener specified at 12mA. The zener has an incremental resistance r(z) = 30 ohms and a knee current of 0.5mA. The regulator operates from a 10-V supply and has a 1.2k-ohm load.
an unknown sensor is investigated by connecting resistors across the output and measuring the current through them. When a resistance of 30 is connected the current through it is 0.5A. When the resistance is replaced by 20
An electric field in free space is E=(5z^2/e0)az V/m. Find the total charge contained within a cube, centered at the origin, of 4-m side length, in which all sides are parallel to coordinate axes (and therefore each side intersects an axis at +2 o..
Consider the three phase lines symmetrically spaced (fully transposed 7 meters apart using ACSR Dove conductor. Each phase has 4 conductors in a square bundle spaced 0.25 meters apart. a. What is the inductive reactance of the line per mile (60Hz)..
consider a continuos LTI system with step response given by ys(t) = tu(t) - (t - 2)u(t - 2). A. Determine the laplace transform X(s) of the input signal x(t) = u(t). B. Determine the Laplace transform Ys(s) of the step response.
