Combined Digital and Analog Filter

Response

The frequency response of the combined analog

switched-capacitor and digital filters is shown in

Figures 7, 8, and 9. The overall response is clock

dependent and will scale with Fs. Note that the re-

sponse plots have been normalized to Fs and can be

de-normalized by multiplying the X-axis scale by

Fs, such as 48 kHz.
