Is this signal periodic?

Hello everybody!

I have this signal:

My question is if this signal is periodic;

If yes, how to calculate the period in samples and ms?

Thanks

Hi,

The above signal is an exponentially decaying signal, which is a non-periodic signal.

A signal is a periodic signal if it repeats the sequence of values exactly after fixed length of time, called the period.

For a continous periodic signal, the period can be determined by measuring the time difference between the start and the end of one cycle. In a discrete signal, you count the number of samples in a cycle.
