3.3 Digital Filter
The 8-times oversampling FIR digital filter is used to attenuate the image out of band noise component, thus
facilitating the analog filter designing.
The configuration of the digital filter is shown in Figure 3-5. The characteristics of the digital filter are shown
in Figures 3-6 and 3-7.
