6.5.3 Low-Frequency Limit
The low-frequency can optionally be limited by the digital high-pass filter. The cutoff frequency is
adjustable, and can be adjusted to extremely low frequencies thanks to the filter’s exceptionally high
resolution.
Figure 5 shows the low-frequency response for a high-pass filter adjusted to 1 Hz, 5 Hz and
10 Hz, and operating at 4 kHz sampling frequency.
