A long-haul optical transmission link is to be designed under the design constraints that (i) the radius of the core is to be no smaller than 4 ?m, and (ii) a numerical aperture (NA) of at least 0.1
A 1 Gb/s optical link is to be operated at the 1.55 m wavelength. Suppose the dispersion at the 1.55 m wavelength is 17 ps/km-nm, and the attenuation is 0.2 dB/km. For achieving a desired error prob
A second-order PLL is implemented with a non ideal loop filter: H(s) = (s+a)/(s+b) in which b > 0 is very small. (a) Applying small-signal analysis, determine the transfer function between Oe(s) an
Generator 1: 10 MVA, 11 kV, X1s=1.6 per unit on a base using generator A's rated voltage and power Generator 2: 20 MVA, 11 kV, X2s=1.2 per unit on a base using generator B's rated voltage and power
A 3-phase, 11 kV, round-rotor synchronous generator delivers power to an infinite bus whose line-to-line voltage is constant at 11 kV rms. The effective stator resistance and synchronous reactance pe
The disk uniformly rotates in air about its axis (perpendicular to the disk) with an angular velocity . Find the magnetic flux density vector at an arbitrary point along the axis of rotation. Assume
Design a Miller integrator with a time constant of 0.1 s and an input resistance of 100 k ohm. A dc voltage of -1 volt is applied at the input at time 0, at which moment vO = -10 V. How long does it
What closed-loop gain would you expect. If a dc voltage of +1.00 V is applied at the input, what output result. If the 10-k ohm resistors are said to be "1% resistors," having values somewhere in th
draw a state diagram for an FSM with an input gcnt and three outputs x,y, and z. The xyz outputs generate a sequence called a Gray code in which exactly one of the three outputs changes from 0 to 1
Why is the input voltage into the diode in a full-wave rectifier not smooth but the input voltage into the diode in a half-wave rectifier smooth, graphically speaking
Where x(nTs), found above, is the input and x (nTs) is the output of the quantizer. Let the quantization step be delta= 0.5. Plot the input-output characterization of the quantizer, and find the qua
Consider the circuit where the value of the inductor is 1H, the initial current in the inductor is iL(0)=-1A and the input source is Vs(t) = 2[u(t)-u(t-1)] and plot the corresponding current in the
the nature of resistance and expalin why the resistances are not exactly what the color code says it is. Also, explain what effect a resistance has on the voltage of a circuit, as well as the curren
A room has four doors and four light switches (one by each door). Sketch a circuit that allows the four switches to control the light - each switch should be able to turn the light on if it is curre
A runner should STEAL a base if and only if the manager pulls his EAR and BOWs while patting his HEAD, or if he lifts his LEG and pats his HEAD without BOWing, or anytime he pulls his EAR without li
A balanced delta connected load of 15 + j18 ohms per phase is connected at the end of a three-phase line. The line impedance is 1 + j2 ohms per phase. The line is supplied from a three-phase source
For the system described by the following equations, with the input x(t) and output y(t), determine which are invertible systems and which are noninvertible. For the invertible systems, find the inp
A beam of X-rays with a wavelength l of 0.15 nm is directed at a crystal whose planes have a spacing of 0.25 nm. How many diffraction peaks (each arising from a different order n) are possible
Polonium (Po) is the only material which forms a simple cubic crystal (i.e., it is not FCC or BCC) structure with atoms at the corner positions. It is a metal (but it is radioactive so it has very f
A)what is the maximum Doppler for a vehicle speed of 160 km/hr at 900MHz. B)what is the minimum doppler(most negative for this case) C)for this range of Doppler what is the corresponding speed at 1800
Consider an analog periodic sinusoid x(t)=cos (3*pi*t +pi/4) being sampled using a sampling period Ts to obtain a discrete time signal x(n)=x(t)|t=nTs = cos(3*oi*Ts*n+pi/4). Choose a value of Ts for
Write a program that creates an arbitrary sinusoidal waveform with parameters input from the user (via file or keystroke), passes the signal to a function that performs integration and differentiati
a closed conical tank with diameter of 1.50 and height of 3.00 m, sitting on its circular base has 1.00m depth of water. Suppose the tank is upside down and is made to stand vertically that way usin
attend a surplus electronics auction and buy a fancy spot light for the car. when you get home you realized why nobody else bid on the light as it contains a 45-watt, 9 volt bulb and your car ( like
If an object is located at 0.5 times the focal length of a thin lens, calculate the location and lateral magnification of the image. Assume that both sides of the lens are filled with air, that the
