TDA7418
Description of the audioprocessor
4.7
4.7.1
Middle
There are three parameters programmable in the middle stage:
Attenuation
Figure 13 shows the attenuation as a function of frequency at a center frequency of 1kHz.

4.7.2
Center frequency
Figure 14 shows the four possible center frequencies 500Hz, 1kHz, 1.5kHz and 2.5kHz.
