A given peripheral has 3 address lines (allowing access to 8 internal addresses) and requires that address lines A2-A0 to be used. It is desired that this peripheral occupy the hex address range, EB80-EB87 in a given computer system memory map. What should be the correct logic levels on A7-A3 to permit access to this peripheral.
A 75-kVA, 230-V/115-V, 60-Hz was tested with these results: Open-circuit test: 115 V, 16.3 A, 750 W; Short-circuit test: 9.5 V, 326 A, 1200 W a) Determine the voltage regulation at rated load, 0.8 power factor lagging.
A circuit consists of a current source, i=0.030 sin 500t, in parallel with L=20mH, C=50 micro Farads and R=25 Ohms. a. Determine the voltage V across the circuit. b. Solve for the power factor of the circuit.
resistor: a volt-ohmmeter with an internal impedance of 1000 Ω/V and an EVM with an impedance of 11 MΩ. Calculate the voltage indicated by each of these devices.
Design the circuit to establish a dc emitter current of 1mA and provide the highest possible voltage gain while allowing for a maximum signal swing at the collector of +-2V. Use +10V and -5V power supplies.
In other words, your approach should be able to answer the question whether two BDDs are complements of each other, without using the complement operation.
The system uses a 7-cell reuse pattern. If the offered traffic per user is 0.03 Erlangs and the average number of calls per hour per user is 1.5, for an Erlang-C system with a probability of delaying a call being 5%, calculate the traffic load per..
a road between fairbanks and nome, alaska, will have a most likely construction cost of $4 million per mile. doubling this cost is considered to have a probability of 30%, and cutting it by 25% is considered to have a probability of 10%.
A quick description of R5 is needed before the next calculation can be completed. R5 is called a sampling resistor. R5 is put in series with the power supply so it shares the same current as the circuit. This is the TOTAL current
draw a digital design consisting of 2 input AND gates and three inverters, where an inverter is connected to each of the AND gates input and its output. For each of the four possible combinations inputs applied to the two primary inputs.
(a) Using superposition, determine the voltage labeled vx in the circuit represented. (b) To what value should the 2 A source be changed to reduce vx by 10% (c) Verify your answers by performing three dc sweeps in PSpice.
If the accoustic impedance of water is 1.49 and for steel is 42.1, what precentage of sound energy is reflected at a water-to-steel interface? 12.5%,86.8%,43.9% or 43.59%.
A semicircular current elment of radius b is positioned in the x-y plane and has its center at the origin. A second long current element is placed along the coordinate y= -b. If current magnitude I flows through each element in clockwise direction..
