XFUNC22

XFUNC 2.2 is a IBM PC program for DOS. It is an aid to Electronics Engineer who calculates transfer functions using symbolic algebra. It compute the frequency domain transfer function of a circuit in symbolic format, given a circuit description netlist in linear model.

Calculate AC or DC symbolic transfer function in S-domain for Linear Circuits or Z-domain for Switching Circuits.

Accept resistors, capacitors, inductors, dependent sources, ideal opamps, and ideal switches.

Component values can be real numbers, symbols, or user defined symbolic expressions.

Frequency domain results can be transformed to time domain via Inverse Laplace or Z Transform.

Transformation between S-domain and Z-domain results can be done via Forward or Backward Derivatives (Euler Transform), Bilinear, or Impulse Invariant Transforms.

Provide Bode, Gain-Phase, Nyquist, Pole-zero, Impulse, and Step response plots. Plot ranges can be set manually or automatically.
