I have a data set similar to the given image:
Here, Device 1 is sends a signal (i.e., active) at every 2 minutes (periodically) while the devices 2 and 3 sends a signal sporadically.
My question: How can I find that
- Device 1 sends a periodic signal, while the others do not?
- The period of the signal ?
(Please let me know if this is not the correct site for this question).
