|
<p>A simple node to provide various functions across several previous values, including max, min, mean, high and low pass filters.</p>
|
||
|
|
<p>Max, Min and Mean work over a specified number of previous values.</p>
|
||
|
|
<p>The High and Low pass filters use a smoothing factor. The higher the number the more the smoothing. E.g. a value of 10 is similar to an α of 0.1. It is analagous to an RC time constant - but there is no time component to this as the time is based on events arriving.</p>
|
||
|
|
<p><b>Note:</b> This only operates on <b>numbers</b>. Anything else will try to be made into a number and rejected if that fails.</p>
