The problem asks me to convert the transfer function to the time domain and plot it in terms of y(t). We have to use Laplace Transforms because of the nature of the course. Could you please explain what you meant by dividing the two equations out?

Homework Statement Write the differential equation that is equivalent to the transfer function given below. Plot y(t). Assume that r(t) = 4t^{2} Y(s) = 2s^{4}+3s^{3}+2s^{2}+s+1 R(s) = 2s^{5}+3s^{4}+2s^{3}+2s^{2}+4s+2 The transfer function is Y(s)/R(s). Homework Equations I'm a...

hi, can anyone please help me with understanding the criteria for stability of a transfer function? especially with the bode plot, root locus, and nyquist. i've gone through a few search results online and almost every site has different information that feels contradictory to me...

hi, how can i plot the bode plot for this transfer function: [FONT="Courier New"] 100 ---------------- s^2 + 10s + 100 i have 2*ksi*w=10 w=sqrt(100)=10 thus, ksi=1/2 -ksi*w=-10/2=-5 so the overshoot will be at ksi which is at 1/2 and my magnitude is 1. i don't see...

hi, the attached image is from the back of my laptop. i'm trying to figure out how much watts it consumes per hour. i know that power is current multiplied by volts. so its 90.09 watts = 4.62 amps * 19.5 volts. is this the watts per hour? thanks, mark

hi... how can i get A cos (omega t) + B sin (omega t) into this form: C cos (omega t + theta) ? does it equal to A+B cos (omega t - 90) ? i know it has to do with the underdamped response of an RLC circuit. i was looking into phasors as well. any help would be greatly...

honors courses are classes that cover more topics or are very detailed about the material covered. also you get more gpa points upon completion. here in the u.s., classes after undergrad are called graduate (or grad) classes. after grad, they're post-grad or doctoral.

don't worry about physics 2. I'm an EE major and although we covered a lot of topics in physics 2, they're more like introductory material. but do make sure that you're very strong with calculus. especially with gradients, polar and spherical coordinates and transforming integrals from 3d to 2d...

hi, i'm a little...a lot confused about op amps. in english, can someone tell me their purpose? thanks

hi...this question is from a sample midterm that we went over in class today. i still don't understand certain things. I'm hoping someone can explain it to me. --- [FONT="Courier New"]consider three identical-looking coins. Two of the coins are ordinary fair coins (H and T are equally likely...

hi, i took calc 3 and differential equations. that was about a year ago and i vaguely remember what that's about. I'm thinking about electrical engineering and i heard from many that its math intensive. can someone tell me exactly what math is involved? i've been told to look into classes...

that's not 500 exclamation point. it's 500 factorial. should i have used a different notation?

hi...how can i tell which number is larger just from using logic? for example a question says "which is larger 2^1000 or 500!?" the answer is 500! and the hint is: just compare the 500 factors appearing in each expression. i don't understand the hint but more importantly, I'm just not seeing...

i think so. it's like an induced subgraph except without the non-connected vertices?!

hi, what's the spanning tree from the graph shown? it was on a test and I'm curious as to if I'm right or not. what i wrote down was a graph with edges 5, 6, 7, 8 and vertices A, B, C, D, E barneygumble742
