Use the Compress Digital VI to compress digital data when you want to display two or more serial digital signals with the same bit sets on the same row to better visualize the data. For example, if you acquire 10 digital waveform samples and nine waveforms are identical but the tenth waveform differs, compressing the digital data helps you easily find which waveform is different. Compressing digital data also conserves memory resources. Use the Uncompress Digital VI to uncompress digital data you compress.
