Enable Debounce Filter in Signal Express

[ipallis]

Hallo everybody,

I want to measure the frequency from a rotary encoder but I the enviroment is electromagnetical noisy. The encoder is near an inverter and as a result the proper measuring of the pulses is inevitable. I use the 6211 usb ni card. From my search in the forums, I discovered that enabling the debouncing filter will solve the problem but I cannot figure out how this can happen in Signal Express. 

Any suggestions will be helpful. Thank you.

Hi ipallis, 

So the first thing to note is that SignalExpress is not a full scale development environment like LabVIEW. This means that some functions that may be available in LabVIEW will not be available in SignalExpress. Unfortunately I believe this may be the situation you are running into. This article talks about how to enable the debounce filter in LabVIEW: http://digital.ni.com/public.nsf/allkb/220083B08217CFD686257131007E5D2C

Enabling the debounce filter can be done through a property node which is a more advanced function, and likely only available in LabVIEW.
