calculate delta X when Y has a value

[emendezcampa]

Hi all, 

I have a dataset with two channels: (1) a signal which has boolean values (1/0) and (2) time. I want to eliminate the noise of this signal, so I mean giving a value of 0 to the signals which last less than 2 minutes. I guess that first of all, I need to calculate the delta X when Y=1 and once I have can eliminate the smallest values. Do you know which functions could I use for calculating that?

Thanks

Hi Estefania,

What DIAdem version are you using?  DIAdem 2015 has new ChnEvent...() functions that would be the best way to handle this.

Hi Brad, 

I am using Diadem 2012. Does it have any function to handle this?

Thanks

Hi Estefania,

With DIAdem 2014 and previous you will need to use the ChnFind() command to identify the row where the signal is 1, then use it again to determine the next row where the signal is 0, then calcualte the delta time between the two rows to determine if this is signal or noise.  You'll need to put all that in a loop to search for multiple 0-1-0 events.
