5-BAND EQUALISER

The WM8758B has a 5-band equalizer which can be applied to either the ADC path or the DAC path.

The plots from Figure 53 to Figure 66 show the frequency responses of each filter with a sampling

frequency of 48kHz, firstly showing the different cut-off/centre frequencies with a gain of

12dB, and

secondly a sweep of the gain from -12dB to +12dB for the lowest cut-off/centre frequency of each

filter.
