TDA7718N
Description of the audioprocessor
4.5.3
Quality factors
Figure 10 shows the four possible quality factors 1, 1.25, 1.5 and 2.
Figure 10. Bass quality factors @ gain = 14 dB, f_C = 80 Hz
4.5.4
DC mode
In this mode the DC-gain is increased by 4.4 dB. In addition the programmed center
frequency and quality factor is decreased by 25 % which can be used to reach alternative
center frequencies or quality factors.
