L1-01D.17 – Pulse Count Detectors Any signal that exceeds the threshold is considered a pulse. There is no qualification made as to the size and duration of the signal. A pulse count detector will indicate an alarm condition if a number of pulses (typically 2 or...
L1-01D.16 – Theshold Processing Every PIR detector uses some sort of signal processing to determine if the pulses created by the PIR element indicate that motion is present. All PIR’s have a threshold to filter out background noise and signals created by minor...
L1-01D.15 – Signal Processing Examples DualCore: Signals are analyzed in multiple domains, including amplitude, time, frequency and duration. C3: Correlates data from both channels simultaneously, instead of independently processing each MAP: Timing and sequence...
L1-01D.14 – Signal Processing Signal processing is the mathematical analysis of the nature and characteristics of signals Goal is to block out “noise” that leads to false signals The difference between one detector and another is often the sophistication of the...
