5-BAND EQUALISER
The WM8978 has a 5-band equaliser which can be applied to either the ADC path or the DAC path.
The plots from Figure 58 to Figure 71 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.
