1. Derive the eigenvalue equation (2.2.33) by matching the boundary conditions at the core-cladding interface of a step-index fiber.
2. A single-mode fiber has an index step n1 -n2 = 0.005. Calculate the core radiusif the fiber has a cutoff wavelength of 1 µm. Estimate the spot size (FWHM) of the fiber mode and the fraction of the mode power inside the core when this fiber is used at 1.3 µm. Use n1 = 1.45.
Explain why it is unlikely one would encounter a circuit exhibiting a critically damped response in practice. What impact would time and temperature have on a supposedly "critically damped" circuit
Given a four-volt peak to peak square wave, calculate the mean-square error in approximating the wave by only its fundamental sinusoidal component. Assume the average value is zero (no DC offset).
Write the expression for the vector distance of a point in a rectangular room from one corner of the room, choosing the three edges meeting at that point as the coordinate axes. Describe the vector distance field associated with the points in the ..
A silicon sample at T = 300 K contains an acceptor impurity concentration of \(N_{A}\) = 1016 cm-3. Determine the concentration of donor impurity atoms that must be added so that the silicon is n-type and the Fermi energy is 0.20 eV
Identify a particular employer and an entry level position with that employer that you would like to obtain following graduation. Find out what is required to be considered for that position.
An LTI system has an impulse response h(t) = e^(t) u(-t),where u(t) is the unit step signal. (a) Give a differential equation description for the system. (b)Suppose that an input signal is given as x(t) = e^(-t) u(t). Determine the output response.
Two amplifiers(CS) connected in cascade. The input voltage to the first stage has a source voltage Vsig and Rsig= 100KOhm. Rv=10KOhm AND IS CONNECTED TO THE DRAIN OF THE SECOND STAGE. BOTH TRANSISTORS HAVE Id=.25mA and Vov=.25V
A charged parallel-plate capacitor is disconnected from a battery, and the plates are pulled a small distance further apart. For the following quantities, indicate where they increase, decrease, or stay the same.
Each pole of a 100kW, 250v flet-compound generator has a shunt field of 2000 turns and a series field of 7 turns. If the total shunt field resistance is 100 ohms
How does the placement location of ECG leads affect the signal measured Why is the placement of ECG leads on the wrists equivalent to placing them on the chest
Determine the max rms voltage that can be applied to the high side of the transformer without exceeding the rated_flux_density in the core if transformer is supplied by frequency of 50 Hz.
