The DI-01N unit is designed for differentiating or integrating time dependent signals.
A low pass filter system with Bessel characteristic is integrated to realize a distortion free differentiation of very slow signals. Four time constants are available, set with a potentiometer. The selected time constant can be tuned between 0 and 100 %.
In differentiator mode a variable damp factor can be activated (damp potentiometer) in order to avoid instability.
Output signals with DC offset can be adjusted with trim pots. A reset switch and a reset input are implemented to reset the system if necessary.
