A quantum well has a finite-height barrier on one side and an infinitely high barrier on the other. Find the energies for the two lowest states for an electron in the well. The width of the well is L = 1 nm and the height of the finite step is Uo = 1 eV.
It is possible that such a well may not have any bound states at all. Come up with a mathematical expression for the condition that there will be at least one bound state in the well. Your expression should relate Uo and L, along with any other necessary physical constants.
In the electronics business, mark-up is in the order of 100% to 130% at each level of middleman. Let's say that it is 100%. Let's further say that your product passes through three levels of middleman, that your product is produced in accordance
A lossless line having an air dielectric has a characteristic impedance of 100 Ohms. Another line that is identical in dimensions to the air line is fabricated with the air displaced by a dielectric material have an \(\epsilon_{r}\) value of 4.
Calculate the distance, D at which communication from the space craft will be lost again? Assume both antennas are ideal.
A star-bus hybrid topology consists of a main three branch star toplogy with each branch connecting three stations in a bus topology. This toplogy is changed to a new bus-ring hybrid topology with main five station bus topology.
Determine the periods and find exponential fourier series coeffecients of functions. A.) f(t) = 2(cost)(cos2t) B.) g(t) = 3 + 2e^-j2t + 2e^j2t + 2cos4t C.) h(t) = 4
Binary symmetric channel, Assume that we are transmitting binary digits over a binary symmetric channel. Let p(x=0)=p(x=1)=0.5.
What does "transfer function" of a filter represent What do the Amplitude Ratio (Gain) and Phase Angle represent What are the key differences between a real filter (the RC circuit) and an Ideal Filter (please read LPF Treated as an Ideal Filter)
A 6 pole round rotor 3 phase star connected synchronous machine has the following test results: Open circuit test: 4000 V line to line at 1000 rev/min, 50 A rotor current Short circuit test: 300 A at 500 rev/min, 50 A rotor current
The circuit will have as inputs a minimum of two inputs; the binary equivalent of two decimal numbers of not greater than (10,000)10. The circuit will also produce a minimum of two outputs, the quotient and the remainder.
Construct the RC differentiator. Set the channel 1 input coupling switch to dc. Next adjust the dc offset, amplitude, and frequency controls of the function generator to produce the input waveform.
After t = 0, the current entering the positive terminal of a flashlight bulb is given by: i(t) = 2(1 - e^ -10t) A and voltage given by: v(t) = 12e^-10t V Determine the maximum power delivered to the flashlight.
