I've built a simple device, which sends readings from a pulse sensor to a PC.
I get these data:
What technique or algorithm can I use in order to calculate the pulse rate (beats per minute) from these data?
Update 1 (03.06.2013 21:01 MSK): The time series represents my heart beat during approx. 3 minutes. According to Wikipedia, adults have a pulse rate between 60 and 100 beats per minute.
Update 2 (09.06.2013 23:53 MSK): Here you can find signal values, which were measured 1000 times per second during approx. 5 minutes.
