<div style="font-family: 'Calibri', 'sans-serif';">Say I have a
sensor for which a measured baseline signal can be used as a
steady state but some predefined deviation greater than a given
amount can can be defined "interesting" by virtue of an interrupt.
With the interrupt can come a sequence of samples (either polled
or by reusing the same or different deviation for an interrupt)
before the sensor reading changes are declared ended, returning to
the old or a new normal baseline level, and the process is set up
to be repeated. Meanwhile, between interrupts and sample capturing
tasks, a set of samples is compared with previously defined
"signatures" to confirm that a set of samples is "complete" and a
<something> has or has not been detected. I realize that in
many cases there has to be a "moving window" to do with matching
up samples and signatures: I'm just <br>
<div><br>
</div>
<div>I'm looking for the math taxonomy to do with this for making
filters and pattern matchers, but also practical examples that
express specific calculations for use cases.<br>
</div>
<div><br>
</div>
<div>Example: A photodetector w a programmable comparator that
triggers an mcu interrupt when a light level is above or below
threshold, and arrangements for detecting these "signatures":</div>
<div> . The moon obscured momentarily by a cloud</div>
<div> . A passing car's headlights</div>
<div> . Dawn</div>
<div> . A cigarette lighter lighting a cigarette</div>
<div> . A cigarette lighter used in "music concert style"</div>
<div> . Lightning</div>
<div><br>
I guess the ideal would be a few Wikipedia references to help me
begin my education, but some practical examples that allow
correlating the math with code that implements the math would be
much appreciated.<br>

Thanks,<br>
