At a design review for your first engineering project, you presentthe project to a panel of three senior engineers who will vote onwhether your project should be funded or not. The senior engineerswill vote using an electrical switch with two positions. A vote of yes will be provide five volts at theoutput of the switch. A vote of no will provide ground, or zerovolts at the output. (See figure). If at least two of the engineersvote yes, the project will be funded.This will be indicated by a green LED being lit. Otherwise, the LED will not light and the project will not be funded. Design a logiccircuit that takes the output of the buttons and lights the LED if a majority votes yes.
noncausal, linear, and time-invariant. Determine the impulse response for the system and verify that an LTI system defined by the impulse response you determined satisfies the difference equation.
An enhancement-type NMOS transistor with Vt=2 V has its source grounded and a 3-V DC source connected to the gate. Determine the operating state if a. vd = 0.5 V b. vd = 1 V c. vd = 5 V
use a third-order low pass filter with a -3dB frequency of 10 Hz to filter your signal. What sampling rate should you use to make sure any potentially aliasing frequencies are attenuated by at least -40 dB for a. A butterworth filter
A diode is measured to pass 0.31mA at 0.70V forward bias, and 1.12mA at 0.75 V forward bias. What are its n and Is. Assume that kT/q=0.026V. For extra credit, if the diode passes 4mA at 0.9V forward bias, what is its forward parasitic resistance
Efficiency in a power transformer is 98.6 percent when loaded such that its copper losses are five times its core losses. Calculate the per unit resistance of this transformer.
In a 10-μm long bar of donor-doped silicon, what donor concentration is needed to realize a current density of 1 mA/μm2 in response to an appliedvoltage of 1V.
A sphere has a radius d and contains a non-uniform charge density of Pv=Po(1-r/d) C/m^3. (a). What is the enclosed Charge for r d (c). What is the electric field for r
A sensitive IC (integrated circuit) on a circuit board is located 1m from a long power line carrying 10A. The power line generates a magnetic field. You can place a trace on a circuit board with current running parallel to the power line to cancel..
