The controlled variable in a closed-loop system is the direction of a robot arm. Initially, it is at 50o; then it is commanded to go to 15o. When the error is 10o for the first time, what is direction of the robot arm?
Consider a continuous-time LTI system with frequency response of H(j omega) = 1 + j 250 omega/(2 - j 50 omega)2 Find the expression for the magnitude of H(j omega) and sketch its Bode plot (sketch asymptotes and the magnitude curves).
What are the two possible frequencies to which the local oscillator could be set? What bandwidth should the 10.7 MHz IF amplifier have?
Calculate the count that should appear in the timer capture register TC0 if a 125 kHz rectangular wave is inputted on timer pin PT0 while TCTL4 is preset for falling edge detection. Assume a 24 MHz e-clock, TMSK2 was programmed
A rod on the surface of Jupiter's moon Callisto has a volume of 0.3 cubic meters. Determine the weigh of the rod in units of pounds-force. The specific gravity is 4.7 gravitational acceleration on Callisto is 1.25 meters per second squared.
The system contains a door sensor, a window sensor, and a key activation switch. If the switch is on, opening the window will set off the alarm immediately. Opening the door will start a 30 second timer.
A microscope has a 2.70-cm focal length eyepiece and a 0.630-cm objective lens. For a relaxed normal eye (assume a viewing distance of 25.0 cm), calculate the position of the object if the distance between the lenses is 13.5 cm
A three-point symmetric moving average filter, referred to as a weighted moving average is of the form \(y[n]=b(ax[nu22121]+x[n]+ax[n+1])\) (a) Determine as a function of a and b the frequency response \(H(e^{j\omega})\) of this system.
A fiber optic audio system consists of an input, a playback head that has a transfer function of .7, an amplifier with a gain of 6 and a speaker system with a transfer function of .4. Find the output for an input of 0.08V
A 6 pole round rotor 3 phase star connected synchronous machine has the following test results: Open circuit test: 4000 V line to line at 1000 rev/min, 50 A rotor current Short circuit test: 300 A at 500 rev/min, 50 A rotor current
