14. What is Digital Signal Processing?
Monicon's controllers use a technology known as "Digital Signal Processing" (DSP) to reduce the incidence of false alarms caused by spurious or unwanted signals from the sensor or the detector.
While the technology behind DSP is rather complex, it can be explained in simple terms as follows:
DSP is a technique where the signal from the sensor is analysed by the the controller's on-board computer over a period of approximately 3 seconds. The on-board computer takes several hundred samples of the sensor signal over this time period and through a series of mathematical algorhythms and formulas can determine if the sensor signal indicates a gas concentration or if the sensor signal indicates, for example a humidity change, radio frequency interference, electromagnetic interference, vibration, etc.
