Design a noninverting amplifier with gain of 20. Maxium opamp output current of 0.5 mA should occur for maximum outputvoltage of 8 V.
A motor with efficiency of 76% supplies 20 hp to a load. it's power factor is 0.6 (lagging). A voltage of 440 VAC (RMS), 60 hz is applied to the motor a) what is the real power applied to the motor in Watt
A CS amplifier using an NMOS with gm = 3.8 mA/V is found to have an overall voltage gain of -16 V/V. What value should a resistance RS inserted in the source lead have to reduce the overall voltage gain to -8 V/V
A certain antenna has a radiation resistance of 51 ?, and an ohmic (loss) resistance of 10 ?. If a current of 2 A is driving the antenna, calculate the following: a) the power radiated. b) the power lost due to heat.
a combined -cycle, natural gas fueled power plant rated at 250 MWe has an efficiency of 65%. find the amount of fuel required per day and per 30 days.
Design a 4-bit serial equality comparator. That is, if we have a3a2a1a0=b3b2b1b0, then eq=1. Note that a3a2a1a0 is stored at register 1, while b3b2b1b0 is stored at register 2.
The magnitude of the current in a RL circuit decreases at a rate of 2000 A/s at t=0 and 100 A/s at t=.2s. At what time has the energy stored in the inductor decreased 1 percent of its intial value.
A 5-element uniform linear array with inter-element spacing of λ/2 is to have maximum radiation in the direction θ=60° , find the current phases , find the directions of null radiation , hence sketch the radiation pattern , find also the relative ..
Determine the distribution of the number of customers waiting in the queue.
A circular line charge of uniform line charge density q(C/m) is located in z=0 plane with its center at the origin. Determine, a. The electrostatic potential V at a point along the z-axis (0, 0, z) b. The electrostatic field E a point along the z-axi..
Design a buck converter that has an output of 12 V from an input of 18 V. The output power is 10 W. The output voltage ripple must be no more than 100 mV p-p. Specify the duty ratio, switching frequency, and inductor and capacitor values.
explain the dilation, erosion, closing, and opening operations on a binary image B with a structured element S. ( you need to use the symbolic notion for the operators, but need not provide the precise mathematical definitions
A saw, fan, and lube pump all go on when a start button is pressed. Pressing a stop button immediately stops the saw but allows the fan to continue operating. The fan is to run for an additional 5 seconds after shutdown of the saw.
