An amplifier with an input impedance of 50 K-ohm, an open circuit voltage gain of 150 V/V, and an output impedance of 100 ? is connected between a 5 K-ohm signal source and a 1 K-ohm load.
a) Find the overall voltage gain Gv.
b) Find the current gain defined as the ratio of the load current to the current drawn from the signal source.
Power Systems Theory Definitions and Formulas, Define, (a) The fault level of a system or unit in a system, (b) base MVA
Select f and K so that the steady-state error to a ramp input is less than or equal to 25% of the input magnitude.Determine the percent overshoot for a step input for the design selected in part (b).Use MATLAB to plot y(t) for a step input R(s).
a. If the signal is passed through an envelope detector, determine the output of the envelope detector. Is demodulation satisfactory b.What is the ratio of the max to min value of the signal at the output of the envelope detector
1. Express the Boolean function f(X,Y,Z) = XY + X(Y + Z) in sum of products form showing the sum all nonzero minterms. 2. Express the Boolean function f(A,B,C,D) = A(B + BC) + ACD in sum of products form showing the sum all nonzero minterms.
1) 70 lbs/hr of steam at 300 psia, 500oF passes through a turbine which expands it to a pressure of 30 psia. If the turbine operates with an efficiency of 70%: a) What is the temperature of the steam leaving the turbine
trace how the electrons and holes move through the device under the two different biasing conditions. Explain how these three devices work in terms of holes and electrons.
Calculate the required thickness [in x-direction] of a silicon wafer in nm to create an 0.2 eV energy difference between the two lowest Enx energy states, use mn*= 0.3 x mo with mo = 9.11x10-31 kg. Assume the y and z-direction infinitely long.
A 25MVA, three phase, 13.5kV, Y-connected, two pole, 60Hz synchronous generator was tested by the open circuit test and short circuit test and tabulated in table 1. If the armature resistance is 0.24 ohms per phase.
An additional variable power factor load is to be added to the factory. The new load will add 320kW to the factory. The power factor of the variable factor load is to be adjusted so that the overall power factor of the factory is 0.96 lagging.
Write a function called Balloon that will accept a single variable named S. The function should replace S with the square of S and repeat this process until S is either greater than 10^15 or less than 10^-15.
1) Determine the resistance range for resistors with the following color codes: a. Red-Orange-Orange-Silver b. Gray-Red-Red-Gold c. Yellow-Purple-Yellow-Gold 2) Determine the color code for the f..
A 4 MHz time-harmonic uniform TEM plane wave that is traveling through a lossy nonmagnetic medium has an amplitude that attenuates by 20% for each meter of propagation. The electric field of the wave leads the magnetic field by 35°
