A system is described by an impulse response h(t) = delta(t - 2) - delta(t + 4) Sketch the system response y(t) = h(t) * f(t) (convolution) to the following inputs:
(a) f(t) = u((3-t)/2)
(b) f(t) = Triangle((t-4)/2)
Construct a 2 rung ladder schematice with an AC source with overload protection in the main line, the schematic will contain 1 rung with a lamp load controlled by a N.O. Push button. On the second rung there will be a N.C.
Calculate transformer efficiency when delivering 20 kVA at 200 V at 0.8 pf lagging
An RC circuit has a capacitance C=100μF. The voltage across the capacitor is vc= 141.42 sin1000t. Find the instantaneous expression for the current. If a voltmeter is connected across the capacitor and an ammeter in series in the circuit,
What is total internal reflection? Discuss the nature of the reflection coefficient and the manner in which the boundary condition is satisfied for an angle of incidence greater than the critical angle for total internal reflection.
In the accompanying passage, from Refuge: An Unnatural History of Family and Place, what was Williams endeavoring to pass on about the administration?"Over and over, the American open was told by its administration, notwithstanding blazes, rankles, a..
It is observed that a straightened paper clip can be twisted through several revolutions by the application of a torque of approximately 60 N.m. Knowing that the diameter of the wire in the paper clip is 0.9 mm, determine the approximate value of ..
A 60 Hz, 765 kV three-phase overhead transmission line has four ACSR 1113 kcmil 54/3 conductors per phase. Determine the 60 Hz resistance of this line in ohms per km per phase at 50o C.
What is the number of Bohr magnetons for an iron atom and a cobalt atom? What is the number of Bohr magnetons for iron and cobalt ferrite?
Determine the DTFS representation for this sample set using the orthogonal basis method. Also, express the result in magnitude and phase form.
A design problem: As we said earlier, the backbone of any design is ‘thorough analysis' of the problem or circuit at hand. We have analyzed above the voltage divider circuit. Utilizing the above analysis, determine R1 and R2 of a voltage divider c..
Consider two-dimensional conduction in the semi-circular cylinder shown.- Write the heat equation and boundary conditions for steady state conduction.
Let the input to a singly-balanced mixer, f(t), be given by V0 Sin (2 pi fs t). The local oscillator input p(t) is a square wave, alternating between 0 and +1 volt. The freqency of the square wave is 10 MHz, while for the input, fs is 100 KHz.
