The DAC channel consists of optional filters for de-emphasis and bass, treble, midrange level adjustment,
speaker equalization, and 3-D effects processing. The de-emphasis function is implemented by a programmable
digital filter block with fully programmable coefficients (see Page-1/Reg-21-26 for left channel, Page-1/Reg-47-52
for right channel). If de-emphasis is not required in a particular application, this programmable filter block can be
used for some other purpose. The de-emphasis filter transfer function is given by:
where the N0, N1, and D1 coefficients are fully programmable individually for each channel. The coefficients that
should be loaded to implement standard de-emphasis filters are given in Table 2.

The 48-kHz coefficients listed in Table 2 are used as defaults.
In addition to the de-emphasis filter block, the DAC digital effects processing includes a fourth order digital IIR
filter with programmable coefficients (one set per channel). This filter is implemented as cascade of two biquad
sections with frequency response given by:
The N and D coefficients are fully programmable, and the entire filter can be enabled or bypassed. The structure
of the filtering when configured for independent channel processing is shown below in Figure 26, with LB1
corresponding to the first left-channel biquad filter using coefficients N0, N1, N2, D1, and D2. LB2 similarly
corresponds to the second left-channel biquad filter using coefficients N3, N4, N5, D4, and D5. The RB1 and
RB2 filters refer to the first and second right-channel biquad filters, respectively.
