Two statistically dependent random variables x1 and x2 are applied at the inputs to a threshold detector , the output from which is equal to the number of inputs that exceed the threshold T. Thus, y = 0, 1 or 2. Determine the density function pY (y) in terms of pX1X2(x1, x2) and T.
The power factor of a load connected to a 120-V 60-Hz source is raised from 0.866 lagging to 0.966 leading by connecting a 110.5-?F capacitor in parallel with the load. Determine the load current I1 and the circuit current IT.
Two components of linear distortion produced by transmitting asignal through an LTI (linear time invariant) system: Amplitude distortion - the frequency components of the input signalare transmitted through the system with different amounts of gain..
Despite the advantages to the synchronous alternator there is a downside and this has to do with keeping the load balanced on such a machine. Why is balancing the load so important to the synchronous alternator?
A proportional control system id to be used to control the wing flaps of a jet airplane. The wind load is expected to cause as much as 600 in*lb of torque. The system should be able to keep the flaps to within 5 degrees of the set point.
design and construct a circuit for a cookie vending machine. The machine sells cookie for 75 Yen each. Assume that there are only 25, 50, and 100 Yen coins. Three different types of coins can be denoted by three different switches on the board, re..
Using the results of (1) design a resistive network with an equivalent resistance of 3 kohms using 2 resistors with the same value from those: 1k, 1.2k, 1.5k, 1.8k, 2.2k, 2.7k, 3.3k, 3.9k, 4.7k, 5.6k, 6.8k. Find an expression for the equivalent res..
The phasor voltage Vab in the circuit is 480 /0° V (rms) when no external load is connected to terminals a,b. When a load having an impedance of 100 j0 Ω is connected across a,b, the value of Vab is 252.9822 /-18.3449° V (rms).
A 3-bit " comparator" circuit receives two 3-bit numbers, P = P2P1P0 and Q=Q2Q1Q0. Design a minimal sum-of-products circuit that produces a 1 output if and only if P
Assuming a uniform current destiny, Find the inductance per meter of length of a coaxial conductor with and Inner conductor of a radius .5 cm, Outer conductor having an inner radius of 2.5 cm and and outer radius of 2.7 cm.
The voltage and current at the terminals of the circuit element are zero for t 0 they are v = 90-90e^(-1000t) V i = 50e^(-1000t) mA A) Find the maximum value of the power delivered to the circuit B)
The charge is release from rest and accelerate through a potential difference of 100000v. (a) Find the speed of the sphere after the acceleration. (b) if the sphere (which is already up to its max)is fired directly at a fixed (can't move) charge q..
