How can I integrate signal from t0 to t1

[rostov]

My problem is: I use USB6251 to receive signal Y continuously, which proportional to dX/dt. I have to calculate signal X in the interval from t0 to t1. I known that can use integralx(t) to integrate this signal continuously, but I don't know how to calculate this integration in the given interval (t0 to t1).

Plz help

Thank in advance.

Quick thought: Can you separate the part of the signal you want and then connect that to integralx(t)?

From what I understand here, you're calculating X (the integral of your signal) from the moment you start acquiring until you stop. So you have a continuous signal of data? Can you not just chop off the beginning data before t(0), and chop off the data beyond t(1), and what's left is the signal X from t(0) to t(1).

By "chop off" I mean use Array Subset and determine which indices relate to these timing points t(0) and t(1).
