Coincidence Windows

Coincidence Window Accepts Boundary

A tick exactly at the window edge is still a coincidence. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

Two channel ticks are compared on one clock

Channel A ticks at 3 seconds, and channel B ticks at 5 seconds.

The boundary case is accepted

The difference is 2 seconds, matching the 2 second window.
