Figure 16 Notch Filter Responses

DF1 FILTER

The DF1 filter is part of the SE1 block. This provides a direct-form 1 standard filter, as illustrated in

Figure 17. All of the filter coefficients are programmable for the left and right channels independently.

The default coefficients give a transparent filter response.
