CS4327
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.
