ACL Channel Maths - Filter Function

[JayDee]

Hi,
For the ACL's (and assume the ADL's), what type of filter is used in the channels maths, i.e. by time or by samples.
And what units is the Filter constant in... ms? samples?
Thanks, J.

I have the same question for an ADL3; What is the meaning of the "Value" in "Input 2 - Filter Constant"? Is it number of samples, milliseconds, hertz? Is this a moving average filter or a low-pass frequency filter? There is no documentation in the ADL3 users manual or the online help functions.
