4.9.2.1De-emphasis Filters

The de-emphasis filters used in the TLV320AIC3107 can be programmed as described in the TLV320AIC3107 data sheet, using this tab (Figure 18). Enter the coefficients for the de-emphasis filter response desired. While on this tab, the de-emphasis response is shown on the Effect Filter Response graph; however, note that this response is not included in graphs of other effect responses when on other filter design tabs.

4.9.2.2DAC Digital Effects Filter

The digital audio input stream can be routed through the digital effects filter in the codec before routing to the DAC to allow custom audio performance. The digital effects filter cannot operate on both the ADC or DAC at the same time. The digital effects filter operation is discussed in Section 4.9.3
