Assignee: ROCKWELL COLLINS, INC.
Field: Measurement (Instruments)
Classification: CPC G  H | IPC G  H

Claim 8:
9. A method, comprising:
receiving, by a processor of a digital pulse analyzer unit (DPAU), ambient data from an environment;
calculating, by the processor, an average amplitude of the ambient data as a measure of a noise floor;
receiving, by the processor, a signal of interest found by the signal of interest exceeding a noise riding threshold, the noise riding threshold being offset from the noise floor;
calculating, by the processor, a running average for amplitude and frequency of the signal of interest;
calculating, by the processor, a running variance for the amplitude and the frequency of the signal of interest;
using, by the processor, the running average and the running variance to provide an adjustment to limits for modulation detection;
using, by the processor, an offset from the noise riding threshold to provide a signal qualification minimum amplitude;
qualifying, by the processor, the signal of interest based at least on the signal qualification minimum amplitude;
creating, by the processor, a secondary signal qualification minimum amplitude in addition to and upwardly offset from the noise riding threshold, wherein the secondary signal qualification minimum amplitude results in signals with a higher signal to noise ratio than the signal qualification minimum amplitude;
adjusting the secondary signal qualification minimum amplitude, wherein as the noise floor changes the secondary signal qualification minimum amplitude moves with the noise riding threshold and the noise floor; and
qualifying, by the processor, a second signal of interest based at least on the secondary signal qualification minimum amplitude.
