There are two parameters programmable in the treble-filter stage.
1. Control Range: Figure 11 shows the control range in the frequency domain at 12.5kHz
center frequency.
Figure 11. Treble control range; f_C= 12.5kHz, Q= 1.0
2. Center frequency: Figure 12 shows the four selectable center frequencies at a gain of
15dB
