Aha. Thanks for the help.

The problem is whether the following matrix is diagonalisable: 4 0 0 1 0 0 1 0 0 0 1 0 -2 0 0 0 0 0 3 0 0 0 0 -2 -1 I can't think of any easier way to find the e'values other than by brute force, which looks hard for a 5x5 matrix (or Matlab :smile: ), save to say that...

All I want to know is if a number and its negative appear as eigenvalues of a matrix, are they considered distinct? I have 4,1,-2,3 and -1 as eigenvalues of a particular matrix, but I can't get 5 linearly independent eigenvectors (to diagonalise the original matrix). I've plugged away and...

Ok, so with the availability of caps I have got what seems the perfect solution. I've got a non inverting amp with an Rf of 15k and a Zi consisting of a series 100nF cap and a 5k resistor. Solved! With an ideal op amp this seems perfect. The only problem I can see is that when I run it...

I have to design a circuit that will undo the effects on a signal passed through a "black box". I have already determined that I have a pole at 500rad/s and a zero at 2000rad/s and a max phase shift of ~ -37* at ~950rad/s. It has a DC gain of 1 and a HF gain of ~0.25. The input signal is a...
