Thanks for the response. What I actually wanted to do was measure the time difference between peaks. For my project, the input won't be a signal generation, but a signal from a microphone receiving sound from a subject's heart. My question really is: is there a VI that outputs time difference between peaks?

Thanks,

Hi everyone,

I'm working on creating a counter (specifically creating a heart beats per minute display for a school project). I'm using a trigger and gate express VI along with a statistics express VI with the 'time delta' output enabled. What I want for now is a display of time in between triggered samples which I don't seem to be getting. The time delta numeric indicator displays a constant value. I'll attach the VI (which includes a control to change frequency of a sine wave, time delta should decrease as frequency increases). Any ideas?

Thanks,

Joe
