convert sine wave to digital output

[u of u]

Hi,

I'm using pci-6251 and Labview 8.
I have an input analog sine wave which I want to convert to an output  TTL pulse (with the same frequency). I also want to be able to control the width of the TTL pulse.
Can anyone give me some advise?

Thank you,
Shafran

Shafran,

This KB should be a great starting point for your application. You can change the width of the pulse by changing the duty cycle.

Can I Create a Digital Pulse Train That is Synchronized with My Analog Input Signal?
