    Step response and peak response of a transfer function

    I was able to solve this problem with the aid of Matlab, but 10 can not be used as a damping constant, or the system would be overdamped, and not have the response that was needed. I was able to conclude the damping constant with the use of the software I have, but would like to be able to...

    Balanced and unbalanced lines

    Balanced lines use a differential signal, that consists of two wires. The notion of differential is that any noise that occurs on one conductor will appear on the other, and since one signal is referenced to the other a common signal nulls out, leaving only the intended signal. Unbalanced lines...

    Step response and peak response of a transfer function

    Homework Statement The open loop transfer function to a unity negative feedback system is given as: G(s)=50/s(s+10) Homework Equations Unity feedback is used in this problem, and the system input is a step function. Y(s)=50/s(s^2+10s+50) The Attempt at a Solution I have...

    Balanced and unbalanced lines

    A balanced line propagates a differential signal, where both conductors are in close enough proximity to each other that, when exposed to an interference, will have negligible effect to the signal that is transmitted. This is because both conductors of a balanced line are isolated on both sides...

    Need help picking out an oscilloscope

    One thing to keep in mind when purchasing equipment is the cost of accessories, and how well the equipment will be serviced if there is a problem. A seller may lower the cost of the scope, knowing that you will need service or accessories later.

    Can Electromagnetic Welding Tables Improve Welding Accuracy and Efficiency?

    I don't see any problem, as long as the electromagnet is isolated from your work. Permanent magnets are already used as temporary clamps for welding, so there should be no problems using a different source of magnetism.

    Inverse Laplace transform Signals and systems

    Thanks. The X(s) comes from the formula that was given in the assignment. x(t)=(5/7)(e^-t)-(12/7)(e^-8t) When I was writing my explanation, I think I found an error. I will post back.

    Inverse Laplace transform Signals and systems

    I am guessing that the mistake made with the X(s) and H(s) terms is that I simplified and ended up with unfavorable numerators. I am going to try using : H(s)=1/(s+ω^2 )+4/(s^2+ω) X(s)=1/(s+2)+1/(s+9) and calculate from there. Is this correct? Thank you.

    Inverse Laplace transform Signals and systems

    Homework Statement Compute Y(t). Homework Equations Y(s)= (s(2s+11)+ω(8s+4ω^2))/((s^2+ω^2)(s+9)(s+2)) The Attempt at a Solution (s(2s+11)+ω(8s+4ω^2 ))/((s^2+ω^2)(s+9)(s+2))= A/(s^2+ω^2 )+B/(s+9)+C/(s+2) Every example I have looked at does not have the ω variable, but I...

    Engineering Circuit with Dependent Voltage source

    In the circuit a current of 4A is given. Since there are two branches, and one branch has ix and the other has 2ix, the total current is 3ix. If 4A is divided by 3, then ix=4/3.
