Get previous value or interpolated value from past

[Mattheus Sant'Anna]

Hello,

Is there any function or manner to get the value of a signal in the past? For example, let's us suppose that I have a signal A, and I would like to make the following calculation:

Calculation = (A( * - 5s) + A(* - 10s) + A(* - 60s))/3

Where A(*-t) would get the value of A at 5 seconds ago, it could be interpolated value or the nearest available value.

Any help?

Regards,

Mattheus

Hi Mattheus,

You can do this by using the move (v49+) or delay (<=v48) function. For example, your equation would be:

($signal.move(5s)+$signal.move(10s)+$signal.move(60s))/3
