A new semiconductor has Nc = 1019 /cm3 and Nv=5 x 1018, and Eg = 2eV. If it is doped with 1017 donors (fully ionized), calculate the electron, hole, and intrinsic carrier concentrations at 627K.
Supply the quantisation levels (including zero) that are available. Do this for both the three and 4-bit ADC in table form. What is the resolution of each quantizer?
Attenuation of received power with change in transmission frequency and distance between the antennas
In other words, your approach should be able to answer the question whether two BDDs are complements of each other, without using the complement operation.
A 4KHz audio signal is transmitted by using a PCM system and the quantization level, L is 256. Find transmission bit rate.
Surface integral for jet engine. The air-gas exhaust velocity from a jet engine varies linearly from a maximum of 300 m/s at the center of the circular exhaust opening to zero at the edges. If the exhaust diameter is 1.6 m, find thq exhaust flow.

a resistor is required for an application that requires its value to be no less than 7.1k ohms and not more than 7.9k ohms. determine the nominal value and the maximum tolerance of the resistor you could use. explain.
Determine the Laplace transform of f(t) = +5e^-4t + 12sin 3t. If the voltage across a 2 F capacitor is initially zero, what is the instantaneous power if the current is A?
Derive the dynamic model and average value circuit of a buck converter assuming the ESRs of the inductor and capacitor are not equal to zero.
Calculate the S/N ratio for a receiver output of 4 V signal and 0.48 V noise both as a ratio and in decibel form. (69.44, 18.42dB)
What is the advantage of using a double-break contact instead of a single-break contact?
the magnetic circuit shown with a mean core length of 52 cm and a cross sectional area of 18 cm^2. the length of the air gap is 0.14 cm. Determine the battery voltage required to obtain a flux density of 1.2 T in the air gap. Use the magnetization..
