A digital low-pass filter is placed between the Hall A/D converter and the DSP, and can
be used to reduce the noise level. The low-pass filter has a constant DC amplification of
0 dB (Gain of 1), which means that its setting has no influence on the internal Hall ADC
value.
The bandwidth can be set to any of 8 values.
