1. Calculate the relative permittivity of the dielectric material used in a parallel plate capacitor if: a) S=0.12m2, d=80µm, vo=12v and the capacitor contains 1µJ of energy. b) Stored energy density is 100J/m3, vo=200v and d=45 µm. c) E=200kv/m , ρs=20µc/m2, d=100 µm
1. prove using theorems of boolean algebra that bc ba ac abc a. 2. given the following function in sum-of-product
Assume a thermocouple generates a linear voltage from 20 mV to 50 mV when the temperature changes from 750 degrees F to 1250 degrees F. How much voltage will be generated when the temperature of the thermocouple is at 1000 degrees F
If you have 1024 samples of a discrete-time band-limited signal sampled at a rate of 100MHz. what is the time period between samples. If you take a 2048 point FFT of the sampled signal, what will be the freuqency spacing between the output samples..
Assume that this whole system is linear, so that, if the pressure on a sprinkler is halved, the area covered (as well as the flow rate) will be halved. This is true until the pressure is reduced below 20psi, at which it does not work at all.
Brown and Vranesic. Problem 6.28 - Repeat Problem 6.26 using T flip-flops. Design a three-bit counterlike circuit controlled by the input w. If w = 1. then the counter adds 2 to its contents, wrapping around if the count reaches 8 or 9.
What are the most common insulators used for extremely high voltages. Explain your answer with, at least, two points foreach insulator. Hint. they can withstand much highertemperatures than rubber insulation.
Find an expression for the scalar electric potential at any point on the axis of the ring. Indicate clearly your coordinate system and its geometry. Check the limiting case as the field point recedes to infinity.
A linear time-invariant system is described by the difference equation y[n]=x[n]+x[n-4] (a) Find its impulse response h[n]. (b) Find its system function H(z). (c) Plot the poles and zeros of H(z) in the z-plane.
Compute the power levels of the 2nd, 3rd, and 4th harmonics relative to the fundamental output signal for the Class C amplifier. compute the Fourier coefficients for the harmonics of the clipped sinusoid that results from the partial conduction an..
A 2-input NOR gate has inputs A and B. If the output of the gate remains LOW independent of the state of input A, what can be deduced about B
A Si bar is 0.25 cm long and 500 ?m2 in cross-sectional area. It is grounded at x=0 and biased at +20V at x=0.25 cm. Find the resistance and the current at 300K (a) when the Si bar is doped with 2×1017 cm-3 arsenic
A transmission line having a 50 ohm characteristic impedance is to drive a load of 200 ohms. 1)What is the reflection coefficient if the line is connected directly to the load 2) What is the standing wave ratio on the main line under the conditions o..
