A device with input x(t) and output y(t) is characterized by: y(t) = x2(t).An FM signal with frequency deviation of 90 kHz and modulating signal bandwidth of 5kHz is applied to this device. What is The bandwidth of the output signal.
design a 100 hp motor controller circuit which has a push button to start and stop the motor. include an external cooling fan and a means to automatically shut down the motor is it overheats. Hint attach thermostat to case of motor.
implement a circuit that generates VGA signals to draw a blue screen on your monitor in a resolution of 640x480. The following materials provide detailed descriptions of how VGA signals operate and some hints on how to design the VGA controller
An unbalanced Wheatstone bridge circuit has resistance arms of 400, 40, 602, and 6000-ohm taken counterclockwise around the bridge. The galvanometer has a resistance of Rg=110-ohm and is connected between the junction of the 40 and 602-ohm resisto..
A three 120 - V power line is Y-connected. The three phase outputs are marked as a,b,c. The neutral is marked as n. The phase sequence is abc. It is connected to a balanced Y- connected load, with the impedance is 12 + j 9 omega.
Current, voltage, and power to a three phase system are measured and found to be 20 A, 550 V and 10.5kW respectively. Determine equivalent circuits per phase as follows: (a)wye connected series combination of resistance and reactance in each phase.
Each single phase transformer has an identical number of turns in the primary and secondary windings. If a line-to-line voltage of 480V is applied on the wye windings, compute the line-to-line voltage on the delta windings.
Plot the signal x(n) 0
Given 100-MHz clock signal, derive a circuit using D flip-flops to generate 50-MHz and 25-MHz clock signals. Draw a timing diagram for all three clock signals, assuming the flip-flops introduce no delay.
The sampling frequency in a DSP system is fs=8 kHz. Anti-aliasing filter used in the system is the second-order Butterworth filter with cutoff frequency of fc=3.4 kHz. What is the percentage of aliasing level at the frequency f=2.5 kHz
What is the primary purpose of a resistor in series with a LED being driven by a flip-flop?
You have a laundry room where the following loads are connected to a 208V circuit: 2500W electric base board heater, 600W wash machine, 3600W dryer, and a 1000W iron. All loads are connected in parallel.
A factory is to be supplied with 408Y/277 3 phase, 4 wire electrical service. The total estimated single-phase load is 25 kW, at .9 lagging power factor. The total estimated three-phase load is 250 kW at .85 lagging power factor.
