Switched-Capacitor Filter Time-Domain Response

This design compares two different implementations of a low-pass filter. One is just a simple RC filter circuit with 1 kHz cut-off frequency. The other is an equivalent filter using a switched-capacitor implementation.

See also http://www.systemvision.com/design/switched-capacitor-filter-frequency-r... to see a technique for measuring the frequency response of the filters.
