This is so typical.
A while ago we saw I fed this signal to a schmidtt trigger,which gives me square signals and about 20 posts stated that it would be insufficient to detect a heart rate. Now here we go again, eveidently 20 "will not work" posts is not enough to convince Hatem, so he post again in the hope that someone will say "it will work"

Hatem. it will not work and posting the same question again will not work either.
