An unknown semiconductor has a bandgap of 1.1eV and Nc = Nv. It is doped with 10^15 cm-3 donors where the donors fully ionized. Given that EF is 0.25 eV below Ec, calculate the concentration of electrons and holes in the semiconductor at 300 K and ni.
You are required to determine that this next generation transmission system will require a spectral efficiency of 5 bits/sec per Hertz.

Compute the power levels of the 2nd, 3rd, and 4th harmonics relative to the fundamental output signal for the Class C amplifier. compute the Fourier coefficients for the harmonics of the clipped sinusoid that results from the partial conduction an..
An electric pencil sharpener is rated 240 mW, 6 V is connected to a 9-V battery and a series-dropping resistor Rx needed to power the sharpener. Calculate the value of the series-dropping resistor Rx needed to power the sharpener.
(a)The Avengers (Iron Man, Thor, Captain America, The Hulk, Black Widow, and Hawkeye) are dramatically posing left-to-right for a movie poster. How many unique leftto-right arrangements are there
Implement a high-speed multiplier which will multiply two 2-bit binary numbers (B1B0 and C1C0) using a 16X4 PROM (lookup table implementation). List the content of all the memory locations in the PROM and describe the operation.
Let us assume that a synchronouse 3 phase alternator produces a no-load line voltage of 13.2 KV. if a load having a lagging power factor of 0.8 is connected to the machine, must the excitation be increased or decreased
Explain and discuss the problems presented by electronic discovery in civil actions and how the law has responded.
