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.
