Sorry, i do mean degree! Slipped up cos I am working with a 4th order system. I was worried id have to do it the long way. I did use Matlab but wanted to see if I could work out the answer by hand. Anywat, thanks for the help guys. I really appreciate it!

Hey everyone Im doing control engineering and was wondering what methods i could use to find the roots of a 4th order polynomial? For example: (x^4) + (8x^3) + (7x^2) + 6x = 5 Could I separate that into two brackets of quadratics or will i need to use a really long winded method...

Ok cool, so am I right in saying that (i) the resolution will be 360/(10*72)? Im still not 100% sure about (ii) and for (iii), 0101 1111 0010 in decimal would be: 2^1 + 2^4 + 2^5 + 2^6 + 2^7 + 2^8 + 2^10 = 1522

Hello everyone, I have an exam in a few days and need help with a question on one of the past exam papers. An optical position encoder used on a robot axis has a 10:1 gear ratio, an optical disc with 72 slits, and a 12 bit binary counter. Determine: (i) The resolution of the encoder i.e...

Sorry, that was a bad example. Say I had this transfer function instead: 2 ------------- s^2 + 2Xs + 3 and I had various values for X. I understand how i would plot the various curves on one graph in 2D but is there a way to 3d graph for the same results?

Matlab 3d graph help I'm pretty new to MATLAB so I am sorry if this is a stupid question but how do i produce a 3d graph for a transfer function? Just for arguments sake, a simple TF like this: 2 ------------- s^2 + 2 s + 3
