complex waveform to bit array

[kantabra]

Hi everyone!!

I follow stuck with my thesis.... I need help urgently. I have an array of bits that they are passed by the continuos BB-PSK Gen and I obtain an output complex waveform. This complex waveform contains the I and the Q signal and I want to see these 2 signals in a graph. I can see the signals like sinusoides but I want to see in digital form ('1' and '0'). Any idea??

Attached vi to see better. I want to see the I and Q signals like an array of bits.

Thanks.

Well, you'd have to convert them to digital first. Have you tried a simple comparator operation?

[kantabra]

No, isn't a good solution because the graphs that I'm obtaining are the same....

[smercurio_fc]

So are you just wanting to see each I/Q value as a binary pattern? If so then I'd suggest using the digial waveform graphs. You can find an example on how to use them in the Example Finder (Help -> Find Examples).

The problem is that I don't have digital values in the complex waveform, I have complex values so I can not use the build a digital waveform.

[smercurio_fc]

But you're separating the real and imaginary parts (I and Q). So each of those numbers can be converted to a digital stream for the waveform.

Really? How? I don't find a good example..

You could try something simple, like the attached example.
