Below is a graphical representation a typical pig passage.
PIB = Power In Band
AN = Average Noise
AV = Average Value
DL = Difference Level
HT = High Threshold
LT = Low Threshold
DT = Delta Time
ID5001P_5001_B00
(between Lower Frequency bin (LF) and Upper Frequency bin (UF))
(PIB averaged over Average Noise Time (ANT) period in minutes)
(PIB averaged over Average Value Time (AVT) period in seconds)
(Average Value (AV) – Average Noise (AN))
(user set High Threshold)
(user set Low Threshold)
(time DL goes above HT before returning below LT in seconds)
