A series of 100 measurements is made on the output of an opamp circuit whereby the distribution was found to be Gaussian with mean value of 12.5 mV and a standard deviation of 10 mV. Write an expression for the pdf of these measurements?
A 400-V three-phase, wye-connected synchronous motor delivers 12 hp at the shaft and operates at 0.866 lagging power factor. The total iron, friction, and field copper losses are 1200 W.
A CG amplifier when fed with a signal source having Rsig = 200 ohms is found to have an overall voltage gain of 10V/V. When a 200 ohm resistance is added in series with the signal generator the overall voltage gain decreased to 8V/V.
Derive expressions for the damping ratio and undamped natural frequency of the circuit in Figure in terms of the circuit parameters R, L, and C.
Using a simply supported beam under a uniform couple, show that the reaction forces are equal and opposite in directions with the equivalent nodal forces.
If these nominal non--ideal parameters are replaced, one at a time, by A = 50000, Ri = 1 M and R0 = 150 (each of which is twice as bad as the nominal values), which parameter has the largest impact on the output voltage
An AC induction motor is rated at 1750 rpm with a line frequency of 60Hz. If the motor is operated on a 50 Hz line, what will be its approximate speed in RPM?
If X is a normal random variable with standard deviation 4.00, and if the probability that X is more than 5.52 is .1271 (as shown below), then what is the mean of X? (Note: the diagram is not necessarily to scale.)
Define line impedance. What is its value for an infinitely long line?
A non-inverting operational amplifier circuit is constructed to have a gain of 100 with an input signal of 1 kHz. Would you expect the circuit to have the same gain with the input signal of 1 MHz
Determine the maximum height z above the water surface at which the pump can be located to operate without cavitating.
Construct a table that contains all possible combinations of results and determine the probabilities of getting 0 true outcomes, 1 true outcome, 2 true outcomes, 3 true outcomes, and 4 true outcomes.
If one of the normal vectors to an interface is n-hat = 1/sqrt(13) (3x-hat + 2z-hat) and the electric field just below the interface is E1 = 9x-hat + 2y-hat + 2z-hat, what is the vector part of E1 normal to the interface
