Three single-phase transformers are used to form a three-phase transformer bank rated 18 MVA, 13.8Δ-120Y kV. One side of the transformer bank is connected to a 120-kV transmission line, and the other side is connected to a three-phase load of 10 MVA at 13.2kV and 0.8 lagging power factor.Using the base in the tranmission line of 120-kV and 20 MVA, find the load impedance in per unit to be used in the line-to-neutral impedance diagram.
Gaussian white noise, perfectly band-limited to 0-10MHz, is passed through a perfectly rectangular filter of bandwidth 18 kHz, gain 3 dB, and center frequency 455 kHz. If the RMS voltage of the input noise is 1 volt
The objective is to design a discrete common-emitter amplifier, the common-emitter amplifier is to have the following specifications: single ended input and output Av approximately 20 in the midband 3-dB bandwidth extending from 10 Hz
Suppose you are to construct a logic circuit with inputs {A,B,C} and output {F} The logic is such that "F" is asserted only when "A" or "B" are asserted and "C" is not. First draw and complete the truth table
A sequential circuit hast two inputs (w1 and w2) and one output (z). Its function is to compare the input sequences on the two inputs. If w1 = w2 during any four consecutive clock cycles, the circuit produces a z=1; otherwise, z=0.
Let y(t) he the signal at the output of the LTI system when x(t) is the input signal. The following signals are sampled using a train of impulses with periodicity T, signal x(t) is sampled to obtain xc(t), and signal y(t) is sampled to obtain yc(t..
Consider the following MATLAB code: a = 0:(1/9000):4; % vector of time samples b = 100*a; % instantaneous frequency x = sin(4*pi*b.*a); (a) How many samples are in vector a, b, and x, respectively
The voltage and current at the terminals of the circuit element are zero for t or =0 they are: v = (16,000t + 20)e^-800t V; i = (128t + 0.16)e^-800t A a) At what instant of time is maximum power delivered to the element
Determine the left triceps muscle force (Ftri), elbow joint reaction force (Rj) required to hold this position along with any ground reaction forces (Rg) and/or reaction moments (Mg) in the hand. Show all necessary free body diagrams along with th..
