adaptive filter reduces the amount of filtering by increasing the ALPHA used in the filter. It will
increase ALPHA only up to the limiting ALPHA_MAX value. By doing this, the lag in the filter is
reduced during fast movements. When ALPHA_MAX = 0.99996 = 7FFF Hex, the DC filter will
provide no filtering of the data during fast movements.
The default values as a function of Scanner to sensor separation range are
:
Std. Range Xmtr
Range
ALPHA_MAX
(inches) (fractional)
0 to 17 0.9 = 07333 Hex.
17 to 22 0.9
22 to 27 0.9
27 to 34 0.9
34 to 42 0.9
42 to 54 0.9
54 + 0.9
To CHANGE ALPHA_MAX send The Bird seven words of PARAMETERdata corresponding to
ALPHA_MAX. During CHANGE, you may want to decrease ALPHA_MAX to increase the amount
of filtering if The Bird's outputs are too noisy during rapid sensor movement. ALPHA_MAX must
always be greater than ALPHA_MIN.
SYSTEM MODEL IDENTIFICATION
When PARAMETERnumber = 15 during EXAMINE, The Bird returns 10 bytes which will represent
the device that was found.
