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:
0 — None
1 — Small
2 — Medium
3 — Large
The analog input signal is sampled and converted to a digital signal.
With no filtering applied, the digital value from the conversion is scaled
for use by the microprocessor of the ASD.
If the filtering selection is Small, the ASD averages the last 5 sampled
(digital) values. The rolling average is updated (every 4 μS) and scaled
for use by the microprocessor.
If the filtering selection is Medium, the ASD averages the last 20
sampled (digital) values. The rolling average is updated (every 4 μS) and
scaled for use by the microprocessor.
If the filtering selection is Large, the ASD averages the last 50 sampled
(digital) values. The rolling average is updated (every 4 μS) and scaled
for use by the microprocessor.
False responses to electrical noise are eliminated with no loss in
bandwidth because the value used by the drive is the average value of
several samples.
