A certain internally compensated (dominant pole) op amp has a dc gain of 200,000 and 3 dB bandwidth of 5 Hz. Sketch the Bode plot of the magnitude of the open loop gain to scale. If this op amp is used in a non-inverting amplifier having a closed loop dc gain of 100, sketch the bode plot of the magnitude of the closed loop gain to scale. Repeat for a closed-loop dc gain of 10.
A child is sitting on the outer edge of a merry-go-round that is 18 m in diameter. If the merry-go-round makes 5.4 rev/min, what is the velocity of the child in m/s
To prevent this, a device is placed across the solenoid (inductor) that can hold the voltage to a safe value, say 40V, during transients. If the activating current in the solenoid is 1 amp and its inductance is 100uH
Thre identical impedances are connected to a 3 phase, 415 V, 50Hz Y connected supply, the load draws 21kW at a power factor of 0.82 lagging. Draw all possible wiring arrangements for the load connected to the Y-connected supply.
A gas of density 1.83kg/m^3 and a viscosity of 1.5 x 10^-5 Pa.s is pumped through the tower. The volumetric flow rate of the gas at the entrance is 20 m^3/hour. a. Calculate the pressure drop at the exit of the packed bed.
The doping concentrations in a silicon pn junction are Nd = 5 × 1015 cm^3 and Na = 1017 cm^3. The zero-bias junction capacitance is Cjo = 0.60 pF. An inductance of 1.50 mH is connected in parallel with the pn junction.
There are 5280 feet per mile. There are 3 feet in a yard. Use appropriate parameter passing and return mechanisms. Use appropriate datatypes. For example, with inputs of 1760 yards and 1320 ft, the result would be 1.25 miles.
Consider the collision between two hockey pucks in the figure below. They do not stick together. Their speeds before the collision are v1i = 26 m/s and v2i = 11 m/s. It is found that after the collision one of the pucks is moving along x with a sp..
A) If 220kV, 220 MVA with power factor 0.8 lagging is determined to be at the receiving end, calculate the voltage at the transmitting end. B) If 220kV, 220 MVA with power factor 0.8 lagging is determined to be at the receiving end
1. Express the Boolean function f(X,Y,Z) = XY + X(Y + Z) in sum of products form showing the sum all nonzero minterms. 2. Express the Boolean function f(A,B,C,D) = A(B + BC) + ACD in sum of products form showing the sum all nonzero minterms.
A 150MW alternator generates an open-circut line-t0-line voltage of 12kV at nomial DC excitiation. When the terminals are placed in short-circuit the resulting current per phase is 8000A. a) Calculate the approximate value of the synchronous reacta..
A DC motor has an input of 0-5V and runs at speeds from o to 80 rpm. What duty cycle signal is required to run the motor at approximately 20 rpm
Two charges, q and 5q, are separated by a distance d in air. Assume that the charge q is at the origin and the charge 5q is at x = d. A third charge is placed on the x axis so that the entire system is in equilibrium (there is no net force on any ..
