MATLAB/Octave
- Octave Control Systems Toolbox This is not the same thing that is on Octave Forge here.
Z Transforms
- Relationship between the Laplace and Z transforms
- Convolution and Z Transforms
- Z Transforms and Convolution
- Here is an animation of convolution with continuous signals. Look at it so you understand what is happening with the mechanics of convolution. To convolve with , you flip shift into on the axis, then you multiply it by to get , then you integrate with respect to , so that the convolution is: . The first animation shows this happening with sampled waveforms: and .
- Notice that this is really the same as Polynomial Multiplication.
Discretization
- This is how the c2d zero order hold works in MATLAB/octave. It uses the "exact" solution to the discretization problem.
