The output of a communication channel is Y = X + N where X and N are independent, zero mean, random variables. X represents signal and N is noise. (a) Find the correlation coefficient between the input X and the output Y. (b) Suppose we form an estimate of X (call it 'X') by multiplying Y times a constant a or 'X' = aY. Find the value of the constant a that minimizes the mean square error given by E[(X-'X')^2]. (c) Express the resulting (mean square error)/(standard deviation of X)^2.
A 2.4KV, single-phase circuit suppllies a load of 250KW at a lagging power factor, and the load current is 160A. If it is necessary to improve the power factor, determine the following: (a)The uncorrected poer factor and reactive load.
A pacemaker is programmed to deliver pulses a certain times every minute for a patient with heart block. A 0.5µF capacitor controls the pulse discharges through a 2M resistor. One pulse is delivered every time the fully charged capacitor loses 50%
Consider the current it takes to power a +5V 74xx245(Icc). What is the qualitative difference between the CMOS devices and the non-CMOS devices and the non-CMOS devices What is the explanation for the difference
Design an RC-Low Pass Filter with cutoff frequency at fc=0.5GHz and plot its frequency response and design a parallel resonance circuit with resonance frequency of 30kHz and bandwidth of 20kHz and plot its frequency response.
Let x[k] be a time-domain sequence and X[r] be its DFT. (When written as vectors, unless stated otherwise, always assume the first entry in the vector is at k=0 or r=0, respectively.) If x[k] = [5, 9, 6, 10]
What should be the filter's passband cut-off frequency?(DSP Question).
(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.
The feedback system for the Buck circuit can be analyzed by separating DC component from small signal perturbation. The performance of the feedback can be assessed by examining the Bode plot of the loop transfer function GL(s).
Consider the problem of using a low-voltage system to power a small cabin. Suppose a 12-V system powers a pair of 100-W lightbulbs (wired in parallel). a. What would be the (filament) resistance of a bulb designed to use 100 W when it receives 12 V
A three-phase steam-turbine synchronous generator is connected to an infinite bus. The generator excitation current is IF=1000 A at the time of synchronization with the bus. The generator has a synchronous reactance of Xs =1.5 per unit.
An OpAMP has a unity gain frequency (ft) of 10MHz and a slew rate of 10V/us and AVoc = 120dB at DC (f=0).Assume VCC = -VEE = 15 Volts. a. Approximate the cutoff frequency of the OPAMP itself.
The following heat engines produce power of 95,000 kW. Determine in each case the rates at which heat is absorbed from the hot reservoir and discarded to the cold reservoir. A Carnot engine operates between heat reservoirs at 750 K and 300 K.
