4.6.1
Middle
There are three parameters programmable in the middle stage:
Middle attenuation
Figure 12 shows the attenuation as a function of frequency at a center frequency of 1 kHz.
Figure 12. Middle control @ f_C = 1 kHz, Q = 1
4.6.2
Middle center frequency
Figure 13 shows the four possible center frequencies 500 Hz, 1 kHz, 1.5 kHz and 2.5 kHz.
Figure 13. Middle center frequencies @ gain = 14 dB, Q = 1
