1. A random process has a Gaussian distribution function given by P(x) = 1/√(2πa^2 ) exp?(-(x(x-μ)^2)/(2a^2 ))-∞<x<∞ Determine the average and mean square values of x (t) 2. Determine the time-averaged values of the mean and the power of these two signals, (i) Asin∝t (ii) Ae^(-∝t)
Three single-phase transformer are used to form a three-phase transformer bank rated 13.8kV(delta)/120kV(wye). One side is connected to a three-phase load of 12 MVA at 0.8 power factor lagging. Determine the turns ratio of each transformer
A temperature sensor produces 10 mV for each degree Fahrenheit. Determine the error in temperature reading if 20 mV of noise is added to the sensor output signal when the temperature is 70 degrees.
A three-phase, 3.73kW, 208V, 60Hz induction motor runs at 1746rpm when it delivers rated output power. What are: a) the number of poles of the machine b) the slip at full load
Two spheres separated by each other by 10m have a charge of 0.001Coulomb and 0.003 Coulomb respectively. In between the two spheresis a point of zero electric field. What is the distance from the.001 Coulomb sphere.
The threshold voltage is eight times larger than the absolute value of the bulk potential, while the oxide is 20 nm thick. Find the doping density of the substrate and indicate whether the substrate is doped with acceptors or donors.
The input resistance of the recorder is unknown andlikely to be variable, but it is greater than 10kΩ. Adeflection of 1 cm per milliampere of cell current with anaccuracy of about ±3 percent is desired. What type of ideal amplifier is best suited ..
The power delivered to the element is p(t) = 0.60e-4t W. Compute the current in the element as a function of time, the voltage across the element as a function of time, and the total energy delivered to the element in the time interval 0
A decorative snowman with mass m = 15kg slides down a roof that is inclined at an angle of 30 º from the horizontal. The snowman slides a distance of 6.0m down the roof and off the edge, located 8.0m above the ground.
Include worked solution, a discussion of any differences in the theoretical and measured values and screenshots that show your measurements and paste them into a document
By use of the Nyquist criterion, determine whether the closed-loop systems having the following open-loops transfer functions are stable or not. If not, how many closed-loop poles lie in the right half s-plane.
Suppose a car is traveling at +23.2 m/s, and the driver sees a traffic light turn red. After 0.563 s has elapsed (the reaction time), the driver applies the brakes, and the car decelerates at 7.00 m/s2. What is the stopping distance of the car
