The per-phase impedance of a 600-V, three-phase, Y-connected synchronous motor is 5 + j50 Ω. The motor takes 24 kW at a leading power factor of 0.707. Determine the induced voltage and the power angle of the motor.
A CT signal x(t) can be depicted as follow. It is a periodic function with T0 = 1 micro sec, and amplitude A = 1. The second signal y(t) is a sinusoid function with the fundamental frequency of 900 MHz, i.e., y(t) = cos(2*pi*fc*t)
The transfer function for a circuit is H(s) = (s-1)/((s-1)^2 + 4). What is the natural response of the system? Is it stable?
How can you design a high gain (at least 20dB) operational amplifier with only pmos transistors In most designs, they include both nmos and pmos transistors. Is it possible to substitute the pmos for the nmos
determine Will and compare this value with the values calculated for Problem. 6.12.
Find the magnitude of the electric field at all points in space both inside and outside the slab, in terms of x, the distance measured from the central plane of the slab. What is the field for x = 1.00 cm What is the field for x = 8.00 cm
The bit energy to one-sided noise density at a PCM receiver input is 30 dB. Referring to the figure above, determine the approximate detected S/N ratio (in dB) for 8-bit BPSK with a matched filter detector.
a. What are the effective bandwidths of the two devices?
the block diagram for an elevator controller for a two-floor elevator follows. the inputs fb1 and fb2 are 1 when
On a logarithmic vertical axis from 1ohm to 1Gohm, and a logarithmic horizontal axis from 1rad/sec to 10^9 rad/sec, sketch the following: a) A 1 kOhm resistor and a 1 mH inductor in parallel and (separate curve) in series.
design a combinational circuit that accept a 3-bit number and generates a 6 -bit binary number output equal to the square of the input number.
A second method of development will recover only 50% of the ore deposit , but it will cost only $15 per ton of material removed.Subsequent processing of the removed ore recovers 300 pounds of metal from each ton of processed ore and cost $40 per ..
Design a simple unipolar drive circuit such that the electrical time constant is 2 msec at phase turn-on and 1 msec at turnoff. The stepping rate is 300 steps per second. A three-phase variable-reluctance stepper motor has parameters.
