Analog Filter
Analog filtering is applied after the analog reference signal is converted to a
digital signal. The type of filtering used is Rolling Average over time.
Settings:
None (1 mS)
Small (8 mS)
Medium (16 mS)
Large (32 mS)
Huge (64 mS)
The analog input signal is sampled and converted to a digital signal. With no
filtering applied, the resulting digital value is scaled for use by the
microprocessor of the ASD.
If the filtering selection Small is selected, the ASD averages the last 8 mS of
sampled signal and converted (digital) values. The rolling average is updated
(every 4 µS) and scaled for use by the microprocessor.
This holds true for the Medium, Large, and Huge selections providing a larger
sample to produce the average for use by the microprocessor.
False responses to electrical noise are eliminated with no loss in bandwidth
because the value used by the ASD is the average value of several samples.
