boolean indicator toggle cancellation??

[Moobe]

Hi there,

I have a voltage input coming from a daq usb 6009. I wrote a program to detect for the amplitude of the signal as soon as the input signal goes over a certain threshold. however it seems that sometimes the boolean output of the detection toggles "T-F-T-F" which modifies the amplitude calculation, and gives a wrong answer.

My question is, how can I ignore this toggling and only take the first true for a period of 0.5 sec (the period of the input signal). I want something like a software debounce circuit. 

I hope I was clear.

Thank you
