Q: Obtain 8*1 multiplexer with a dual 4 line to 1 line multiplexers having separate enable inputs but common selection lines. Use a block diagram construction.
Determine zero-input response of (D2+4D+40)y(t)=(D+2)x(t) with initial condition y0(0)=2 & dy0(0)/dt=16.78.
An ideal n+/p diode has only the quasi neutral p region of length L illuminated with light such that GL electrons/cm3-s are generated uniformly throughout the region. There is no photo-generation occurring elsewhere in the diode.
Design a device which will input two 4-bit unsigned numbers and subtract twice the smaller of the two numbers from the larger of the two numbers (That is, input x and y and output x - 2y if x > y and output y - 2x otherwise.)
Determine the transform for g(t) = rect(10t)cos(400 Π t). Use the table of transforms and the convolution property of the impulse function.
a.) Plot x[n] as a function of n and use the definition of the z - transform to find x[z]. b.) Use the z - transform of u[n] and properties of the z - transform to find x[z]. Verify that the expressions obtained above for x[z] are identical.
At some instant, it goes into regenerative braking. Calculate the armature voltage va at that instant, if the current ia is not to exceed 10A in magnitude. Assume that the inertia is large and thus the speed changes very slowly.
Design a low pass active filter that passes frequencies at 900 Hz and below and at these values the magnitude (in dB) of the transfer function is 20+-3(between 23 dB and 17 dB). The circuit's magnitude (in dB) of the transfer function at a frequen..
A votage pulse of amplitutde 10V begins at 5-sec and lasts for 20 msec,which is short compared with the respponse times and time constants of the system.This impulse si then passed through and integrator.
The exciting current for a certain 50 kVA, 480-240V, 60 Hz transformer is 2.5 percent of rated current at a phase angle of 79.8 degrees. Sketch the equivelent circuit and phasor diagram for the no-load conditions and assuming operation is in the s..
Compute y(nT) iteratively for n=0, 1, 2, when, y(-T)=2, and x(nT) = u(n) Hint: the initial conditions are given for negative n. Shift the equation to the right to express x() and y() to eliminate all advances and end up with x(n), y(n)
From the equation for intermediate frequencies, what is thephase angle between the current and electric fieldwhen ωτ = 1, 0.1, and 10. For each case, write an expression for the time dependence of current if the electric fieldvaries as sin(ωτ).
The analog signal cos (200t) is digitized using a sampling frequency of 300 Hz, and a quantization of 8 bits per sample. How many bits will be used to store 2 minutes of the digital signal
