Digital Filtering parameters
A/D converter parameters
Rejection
[50Hz]-[60Hz]
The A/D converter have In-built adjustable low-pass filter with
frequency rejection of 50 Hz or 60 Hz harmonics.
Frequency
6 – 1600 Hz
Filtered measurement frequency is adjustable from 6.25 to 1600 Hz
Bessel low-pass filter parameters
Filter Order
0, 2, 3, 4
For the suppression of periodic vibrations, a Bessel low-pass digital
filter can be applied as an output of the A/D converter.
Minimum cut-off frequency value depends on the A/D converter rate:
0.10 Hz for 6.25 meas/s, 4 Hz for 400 meas/s
Cut-Off Frequency
0.1 to 200Hz
Notch Filter parameters
High & Low
Frequency *
0.1 to 200Hz
Frequency band to attenuate with the digital Notch filter
* May not be implemented depending on eNod4 applicative version.
