Z-Transform Calculator

What This Calculator Does

Compute Z-transform expressions, ROC, poles/zeros, and inverse forms for canonical discrete sequences.

It combines Sequence Type, a (for a^n), ω (rad/sample), N terms to estimate X(z), Inverse Z-Transform, Region of Convergence.

Formula & Method

Notation used in the formulas: R = X(z); x_{1} = Sequence Type; x_{2} = a (for a\^{}n); x_{3} = ω (rad/sample); x_{4} = N terms; x_{5} = z real part; x_{6} = z imaginary part.

Method summary: inputs are normalized to consistent units, core equations are evaluated, then secondary values are derived and rounded for display.

Use this calculator for quick scenario analysis. Start with baseline values, change one driver at a time, and compare how sensitive the results are to each input shown above.
