3-phase line, which has an impedance of 2 + j4 per phase, feeds two balanced three-phase loads that are connected in parallel. One of the loads is Y-connected with an impedance of (20 + j40) per phase, and the other is -connected with an impedance of (65-j40) per phase. The line is energized at the sending end from a 60-Hz, three-phase, balanced voltage source of 120 (3)^1/2 V (rms, line-to-line).
Determine:a) The current, real power, and reactive power delivered by the sending-end source. b.) The line-to-line voltage at the load. c) The current per phase in each load. d). The total three-phase real and reactive powers absorbed by each load and by the line.
To understand di erent signal models To be able to model a discrete-time system and design simple signal processing algorithms.
Fourier transform X(w)=Xreal(w)+j(Xi(w)). Determine and represent the signal y(w) that gives the fourier transform of Y(w)=Xi(w)+Xreal(w)e^exp(j2w).
Find the impulse response fpr the filter? How many nonzero terms does the impulse response contain?
1- Describe the function of the program. DO NOT WRITE THE OPERATION OF EACH INSTRUCTION 2- Assuming that the branch instruction is executed (the branch is taken), comput the number of clock cycles required to execute the loop (DECA or BNE AGAIN)
a) If the internal resistance of a voltmeter is 100x bigger than the output impedance of a circuit, what is the loading error b) If the internal resistance of an ammeter is 10x smaller than the output impedance of a circuit
If someone presses the 1 or First floor button, the elevator should go to the 1st floor, open the door and remain in this state for a small amount of time, then close the door. Assume the elevator takes one clock cycle to travel.
If the distance between two slits is .0500 mm and the distance to the screen is 2.50 m, find the spacing between the first and third order bright fringes for light of wavelength 700 nm.
The potentiometer is designed to rotate 330 degrees to give the full range of possible resistance. However, the actual measurement range that is used is only 165 degrees indicating positions of a liquid sensor float ranging from 0 to 10 cm (empty ..
Calculating a DC Current through the telephone handset, A telephone handset has a resistance of 600 ohm. It is connected to the local telephone exchange at a distance of 5 km by a twisted pair that has a loop resistance of 200 ohm per km
A long hallway has three doors, one at each end and one in the middle. A switch is located at each door to operate the incandescent lights along the hallway. Label the switches A, B, and C. Design a logic network to control the lights.
Consider unsteady diffusion across a membrane of thickness L. Initially, the concentration of solute in the membrane is zero. At time zero, the concentration at x=0 is raised to C0 and the concentration at x=L is maintained at zero.
What is the BER at the output of the receiver in clear air conditions, and the average time between errors? Give your answer in years, days, or hours as appropriate. Assume an implementation margin of 0.5 dB.
