Abstract :
Comparison of the circuit simulator SPICE numerical integrator Z transform with the original system Laplace transform reveals that the trapezoidal method causes only frequency wrapping, while the Gear method generates frequency and amplitude errors. A universal expression for the magnitude of the Gear method error is derived. The theoretical analysis is tested by an example
