Design a power supply using a 24V, center-tapped transformer to supply 12V at 500mA, -12V at 100mA and 5V at 250mA. What is the minimum current rating of the transformer?
(a) Determine the mean, variance, and standard deviation of X. (b) Determine the value for x such that P(-x
what is context based arithmetic coding?and it is calculated .
If we wish to design a communication system which carries voice securely, we need to ensure that others cannot tap into the conversation. In digital transmissions, we can do this by encryption.
design a multirange ammeter with ranges of 1-10mA,0-100mA, and 0-1500mA, using a 5mA movement whose internal resistance is 3.8ohms. draw a circuit diagram of the meter.
Consider the analogue cosine signal y(t) = COS(8.8pit). It is sampled using a sampling interval of T = 0.5 sec. What is meant by the term aliasing in regard to signal sampling What is the minimum sample rate that should be used to avoid aliasing
If these nominal non--ideal parameters are replaced, one at a time, by A = 50000, Ri = 1 M and R0 = 150 (each of which is twice as bad as the nominal values), which parameter has the largest impact on the output voltage
Using this method, create and test a minority vote circuit, a circuit designed to indicate when one or no inputs are HIGH. Determine the appropriate SOP equations, enter, compile, simulate, download, and test your solution.
In a certain system, an electrical heating element was found to increase the temperature of a piece of metal 7o for each amp of current. The metal expands 0.004 in./deg and pushes on a load sensor that outputs 1 V/0.003 in.
Find the nonzero value of ω for which the expression for Z(ω) given is purely real. Give your answer as a function of R, L, and C.
A farmer owns two barns; one north of a creek and the other south of the creek. The farmer has a Cabbage, a Goat, and a Wolf. The Farmer needs to put each item in a barn every night. If the Cabbage and Goat are in the same barn
The heater element of an electric kettle has a constant resistance of 100 Ω ohm and the applied voltage is 250 V. Calculate the time taken to raise the temperature of one litre of water from 15°C to 90°C assuming that 85% of the power input
