Overview and Introduction to the z-Transform (Polynomial & Rational Functions)

Here's the first of a series on the z-Transform. Comments are welcomed.



We introduce the z-transform bringing polynomials and rational functions to help analyze linear discrete-time systems. The discrete-time convolution (or FIR convolution) is equivalent to polynomial multiplication and algebraic operations in the z transform domain can be translated as combining or decomposing linear time-invariant (LTI) systems. The most common z-transforms are rational functions, that is, the… Continue
