Design a full-wave rectifier to provide a dc output of 28V at acurrent of 4A, with a ripple of not more than 3%. A linevoltage of 120V (rms), 60Hz is available.
Then, solve each Problem using hand calculations. A three-phase, 765-kV, 60-Hz transposed line is composed of four ACSR 1,431,000, 45/7 Bobolink conductors per phase with flat horizontal spacing of 14 m. The conductors have a diameter of 3.625 cm ..
There are four oscilloscopes , A ,B, C,D in a laboratory that areequipped with individual indicator circuits. There indicator circuits give our a logic 1 any time the scope mal functions.
At 2GHz, a certain material has εr=2.5,μr=1, tanθ=10-2. Calculate the distance a uniform plane wave can travel through the materialbefore a) its amplitude is reduced by 20%, b) the phase shiftsby 180 degrees, c) the power is reduced by 10%.
Assuming that the effective mass of electrons in the conduction band of GaAs is temperature independent and equal to m* = 0.067mo* , determine the effective density of states Nc at T1= 77k, Tr =300k and Th=450k.
Assuming the input resistance of the load cell is 420 and rated output is 3.0mV/V at the rated capacity. What should be the series resistance that should be added to the excitation side so that the output voltage I reduced to 2.0mV/V
Design a counter that counts pulses on line 'w' and displays the count in the sequence 0,1,3,2,0,1,3,2,0,1. Use D flip-flops in the circuit.
A large brass washer has a 2 cm inside diameter, a 5 cm outside diameter, and is 0.5 cm thick. Its conductivity is s=1.5 X 107 S/m. The washer is cut in half along a diameter, and a voltage is applied between the two rectangular faces of one part.
algorithms to show the differences in the intra prediction in the h.264 and hevc coding standards. it should indicate how the intraprediction in the two coding standards makes a difference in their efficiency.
A certain mixer is producing the following frequencies: 900 kHz, 700 kHz, 500 kHz, and 200 kHz. What are the two most likely input frequencies?
use any extragates in existing ICs for inverters when possible. Connect thecircuit and check its operation. the truth table for F1 and F2obtained from the circuit should conform with the minterms listed.
using 1/(s+2)(s+4) + c find when the poles are repeated and use that value to calculate the impulse response using laplace transforms. Calculate the step response when c = 10 using Laplace transforms.
