N-type Si, GaAs, and 4H SiC are all doped to the level of ND=10^17cm^-3. Determine the volumes of each of these semiconductors that will on avg contain one hole. The intrinsic carrier concentrations are ni=1.02*10^10 cm^-3,ni= 2.1*10^ cm^-3, and 10^-7 cm^-3.
use a third-order low pass filter with a -3dB frequency of 10 Hz to filter your signal. What sampling rate should you use to make sure any potentially aliasing frequencies are attenuated by at least -40 dB for a. A butterworth filter
If a patient is on a drip with a drip rate of f(t) = 150e^0.0167t mL/hr, calculate the amount of substance transferred into the patient over a time period of 10 hours, use time intervals of 1 hour. Compare
When disconnected and fully charged, the voltage across the battery terminals is measured to be 13.8 V. When connected to a load that dissipates 18 W of power, the terminal voltage of the battery decreases to 12 V.
The plant contains six 288MW generators. Given the overall facility efficiency is 76%, and the plant is capable of full output for a duration of 5 hours, determine the potential energy of upper reservoir and the minimum amount of water in gallons ..
Let X be a zero-mean random variable having a variance of 9 and let Y be another zero-mean random variable. The sum of X and Y has a variance of 29 and the difference of X and Y has a variance of 21.
Build and test the operational amplifier summing circuit you designed for the Prelab using 741-type op-amps. Use VA = 2 V and VB = 3 V with power supply rails of ±18 V. Ask your lab instructor to give the correct pin-out of the 741 if necessary.
A transducer produces a sinusoidal waveform with an amplitude of 2.5 VPK and a DC offset of 0 VDC. The ADC input signal range is 0 V to 5 V. Describe the signal conditioning circuit that is needed to use the full-scale range of the ADC.
Why is quality a difficult term to define. how can we improve our understanding of quality?
Assume that the inverters have a delay of 1 ns and the other gates have a delay of 2ns. Initially A = 0 and B = C = D = 1, and C changes to 0 at time = 2ns. Draw a timing diagram and identify the transient that occurs.
A full-wave rectifier circuit having centre-tapped transformer has 500 turns in its primary winding, 25 turns from one end of the secondary winding to the centre tap and 20 turns from the other end of secondary winding to the centre tap.
A 3 phase, 208V, 4 pole, 60Hz, Y connected synchronous generator has a synchronous reactance of 8 ohm. Assume the resistance of this generator is negligible. The machine terminal voltage is maintained constant at 208V (line to line).
Given the ratings of a single-phase transformer - 3kVA 220V/110V 50 Hz, calculate the rated current for the primary winding and the rated current for the secondary winding. The currents in the transformer should not exceed these values during the ..
