Abstract
A description is given of the CAPZ program, which analyzes switched-capacitor filters, computing z -transform transfer functions. It can plot gain and phase versus frequency curves, poles and zeros, and time responses. The transfer functions are computed by FFT (fast Fourier transform) interpolation. Time and frequency responses are computed from the transfer functions, allowing the analysis to be swiftly completed
