convert signal to binary string

[elyan]

Hi all : I get waveform signal (square signal) from scope .. and  I want to convert this signal  to binary string …  

Can I do that in labview 8.5

thanks

hello elyan,

tell a little bit more , but its probably possible with treatments...

best regards

You can do lots of things in LabVIEW. First, you need to specify what you mean by a "binary string". That's not a pre-defined term, and it's a vague one at best.

I'm not entirely clear on what you are asking but you could try this:

Create an array of x and y values from the signal, with however many points you want.

Then convert the values to binary.

Is that what you want to do? If so, I can show you a quick example

Well, to do so you need to first convert the analog signal to binary code. Do you have the square signal from the scope in the first place? If so, you have the array of voltage values that you downloaded from the scope. Then, convert that to zeros and ones by simply putting the array into a comparison function that sees if the value is greater than some voltage, to indicate a 1. This gives you an array of Booleans. At that point it is trivial to convert it to a string. For example, here is one simple way to do it:
