Use the Digital Signal Subset VI to extract individual signals from a digital waveform. The block diagram below shows how you can combine extracted individual signals with other digital data to create new digital waveforms.

The top Digital Signal Subset VI extracts the first and second signals from the digital waveform. The bottom Digital Signal Subset VI extracts the fourth and fifth signals. The Append Digital Samples VI appends the first signal to the fourth signal, appends the second signal to the fifth signal, and plots the resulting two signals on a digital waveform graph.
