U10 of the 4096/4196 schematic is a RAM memory IC. Its operation is discussed in Chapter 16. To enable the chip to work, the Chip Enable input at pin 20 must be made LOW. Write a sentence describing the logic operation that makes that line go LOW. (Hint: Pin 20 of U10 goes LOW if ___________.)
A speaker can be modeled as an inductor LS (the coil that generates the magnetic field to move the speaker diaphragm) in series with a resistor RS (resistance associated with the coil wire, as well as the energy lost to the acoustic output the spe..
Suppose that a three-bus power system has the subtransient bus impedance matrix given below, and that the power system is initially unloaded with a pre-fault bus voltage of 0.98 pu. Assume that a symmetrical three-phase fault occurs at Bus 1, and ..
For the circuit shown, find the input voltage Vs such that the current through R4 is 12A. R4=5 Ohms, R11 = 10 Ohms, R21 = 10 Ohms, R34 = 2 Ohms
How important were the NYCAPS and City Time projects for New York City? What were their objectives? What would have been their business benefits?
(a) Show the truth table of a 3-input-8-output binary decoder (without enable logic). (b) Construct a 3-input-8-output binary decoder using NOT, AND and OR gates (without enable logic).
A 150MW alternator generates an open-circut line-t0-line voltage of 12kV at nomial DC excitiation. When the terminals are placed in short-circuit the resulting current per phase is 8000A.
Design a system using the photoconductive cell
Assume that hydro efficiency is 0.95, the turbine efficiency is 0.9 and the generator efficiency is 92%, estimate the generated electrical power.
·Insulators are a vital part in transmission system they held the overhead transmission line and provide a mechanical support besides they act as an electrical insulator to insulate the line from the supporting system ( pole, tower...etc.)
A continuous-time signal x(t) is sampled at a 10-Hz rate, with the resulting discrete-time signals as given. Find the time constant τ for each signal, and the frequency ω of the sinusoidal signals.
Find the clearance between the conductor and water at a point mid-way between the towers. Weight of conductor is 1 kg/m.
In order to measure the heart rate of the patient, you acquire 8000 datapoints at the Nyquist sampling interval. What is the spectral resolution of the frequency spectrum resulting from these data?
