Phase 'A' of a three-phasee 4.16 kV ungrounded system is solidly grounded. For this fault, calculate the magnitude of the positive, negative, and zero sequence voltages at the fault.
A 1 kHz sine wave signal with a power level -10 dBm is applied to the input of the amplifier. What is the power at the amplifier output?
The single phase for equivalent circuit parameters for the windings of the motor referred to the stator in (ohms/phase) R1=0.2 R2=0.2 X1=0.3 X2=0.3 .the core losses and the magnetization can be ignored.
Design a 3rd order Butterworth High-Pass filter with a Fc of 2kHz and a passband gain of 2. Find the gain and critical frequencies of each individual stage. Plot the gain portion of the bode plot.
Design a basic pacemaker circuit in PSPICE/LTSPICE using a 555 timer, switching transistor and a RC pulse output circuit. Report your design, schematic, input and output waveforms and design rationale.
a sequential circuit has one input (X) and one output (F). The circuit examines groups of four consecutive inputs and produces an output F=1 if the input sequence 0101 or 1001 occurs. The circuit resets after every four inputs.
A 50 V DC power supply is connected to a 100 Ohm load resistor. The tested current flowing through the resistor is 0.49 A. find the internal resistance of the DC power suppy.
For each of the following signals, determine whether it isperiodic; if it is, determine its fundamental (i.e., smallest) period T0 and fundamental frequency f0. (a) x(t) =sin2(2t) (b) x(t) =cos(√3t) +sin(2t)
A line charge of infinite lenght lies along the z axis and carries a uniform linear charge density of ρl C/m. A perfectly conducting cylindrical shell, whose axis is the z axis, surrounds the line charge.
Given a sum-of-products expression, it is possible to write the 1s corresponding to each product term directly on the map without developing an explicit truth table of minterm list, and then proceed with map minimization procedure.
When the variable resistor is adjusted to one extreme position the overall circuit voltage gain should be 3. When the variable resistor is adjusted to its other extreme position the overall circuit voltage gain should be 13.
Design a circuit that will add either 1 or 2 to a 4-bit binary number N. Let the inputs N3, N2, N1, N0 represent N. The input K is a control signal. The circuit should have outputs M3, M2, M1, M0, which represent the 4-bit binary number M.
Using D-type flip-flops, design a synchronous Moore finite-state machine that monitors two inputs A and B, and asserts a scalar output if the number of 1s observed on the inputs is a multiple of 4.
