Beschreibung

The INR-01-T envelope / integrator module is designed for generating envelopes from noisy INPUT signals, e.g. to facilitate detection of oscillations from extracellular measurements in excitable tissues. The INPUT signal is rectified by an “absolute value” circuit and subsequently applied to a “leaky integrator” for filtering. The time constant of integration can be set using a 6-position switch. Additionally, a THRESHOLD can be set in order to mask the noise around the baseline that contains no information of interest, and the OUTPUT envelope can be corrected for OFFSETs before amplification.
