Description
The MINIDAU® advanced amplifier based on the MINIDAU® classic introduces an overload detection, implemented between amplifier part and filter part removing high frequency disturbing signals. Overload conditions are sampled and stored together with actual measurement data. The low pass filter is a pure anti-aliasing filter with an adaptive cutoff frequency that fits to the currently selected sampling frequency. All necessary additional filtering, e.g. according to SAE filter classes, is done during post processing.
