how to produce digital wave

[labmaster]

Just starting to build digital wave replace for counter signal in my DAQ.

I can't get logical AND result as shown in attachment.

In case of irregular pulses, How to build up or edit digital waveform more conveniently?

Hi Labmaster,

It appears to me that in your graph picture, you show "plot 0" offset from "line 1" by 1/2 of a clock period.

This would mean that for each clock period in "line 1" there are two possible states for "plot 0". That creates a

problem when trying to line up the data for comparison.

If you double the sample rate you could get back to a 1 to 1 correlation.

The attached example uses twice the number of samples for the same amount of data (as your example) and allows

you to select a logic operation on the two waveforms.

I hope this is helpful,
steve
