Z Transforms

  • Relationship between the Laplace and Z transforms
  • Convolution and Z Transforms
    • Z Transforms and Convolution
    • Polynomial Multiplication is the same as Convolution
    • Here is an animation of discrete convolution. To convolve with , you flip shift into , then you multiply it by to get , then you integrate with respect to , so that the convolution is: . The animation shows this happening with sampled waveforms: and .
