# Mapping of discrete functions in the z and s planes (example

This content was COPIED from BrainMass.com - View the original, and get the already-completed solution here!

The transform from the s to the z plane using the transform

z = e^sT(s) is used to obtain an inverse transform in terms of s , namely

s = Ln(z)/T(s)

This is then used to find the s plane mapping of z = e^jw

The s palne plot is then made for -pi <= w <= pi and the poles and zeros plotted
