AVERAGE
Syntax
result% = AVERAGE (
input expression%, number of samples%
)
This signal-processing function returns the running average of the input for
the desired number of samples. The number of samples must be a constant
integer value. The input expression is also an integer.
This function can be used only in the SPEED, CLOCK or ENCODER tasks.
AVERAGE requires execution on a regular timebase.
If a step change of 0 to 1000 is applied to parameter #1.21, the output of the
averager will be as follows (assuming a 5ms clock timebase).
Example
CLOCK{
input% = #1.21
#1.22 = AVERAGE (input%, 4)
}
