Physical system modeling, time response and stability
1. Find the differential equations relating input force f(t) and output displacement x1(t) and x2(t) in the system.
(Hint: K, fv and M are spring constant, friction coefficient and mass respectively)
2. Determine the transfer function G(s)=X1(s)/F(s). For the following suppose G(s) = 3 x s+ 13/(s + 1.4)(s2 + 2s + 1.49)
3. Determine the system impulse response in time domain.
4. Draw its root locus and comment on system stability.
5. If the system can be simplified using the system dominant pole technique into G1(s) below, obtain the system response for a unit step input, and estimate the overshot and settling time.
A transmission line with no loss, with Z0= 60 ohms, is operated at 60MHz. The velocity on the line is c. The line is soldered to a ground connection at z=0. Find the input impedance into this line at z= -1.25 meters
An EEG signal from a healthy adult contains clinically relevant frequencies in the range of 0 to 45 Hz. The frequency bands are generally grouped as delta (0.5-4 Hz), theta (4.5-8 Hz), alpha (8.5-13 Hz), and gamma (30-45 Hz).
C program: counting numbers between 0-9, Write a C program that generates one hundred random integers between 0 and 9 and displays the count for each number.
On a logarithmic vertical axis from 1ohm to 1Gohm, and a logarithmic horizontal axis from 1rad/sec to 10^9 rad/sec, sketch the following: a) A 1 kOhm resistor and a 1 mH inductor in parallel and (separate curve) in series.
a road between fairbanks and nome, alaska, will have a most likely construction cost of $4 million per mile. doubling this cost is considered to have a probability of 30%, and cutting it by 25% is considered to have a probability of 10%.
Write a 68000 assembly program to subtract two strings of A15 ASCII characters. The first string is stored starting at $502030. The second string is stored at location $302510. The ASCII character in location $502030 of string.
a sound distribution system has the following outputs 10 watts at 8ohms,5watts at 4 ohms, 15 watts at 16 ohms and 2 watts at 4 ohms if the input to the amplifier is 20 millivolts at 600 ohms how much gain in decibels will be required of the amplif..
The command in AutoCAD can be a time-saver, particularly when you're working in an application where you want to move a door or windows within walls on a drawing and don't want to redraw the walls.
A digital communication system transmits one of the three values -1,0,1. A channel adds noise to cause the decoder to sometimes make an error. The error rates are 12.5% if a -1 is transmitted, 75% if a 0 is transmitted, and 12.5% if a 1 is transmi..
an object hose mass is 200 kg moves at a velocity of 50m/sec and altitude of 200m,both measuredc relative to the surface of the earth. the acceleration of gravity can be taken as constant at g=9.8 m/sq.sec.
Twenty voice signals are to be multiplexed and transmitted over twisted pair. What is the bandwidth required (in bps) if synchronous time division multiplexing is used
Construct a Phasor Diagram to represent the source voltage, source current, voltage drops, VR, and VL across the resistor and the inductor. The diagram does not need to be drawn to scale. However, the values of the items represented must be includ..
