Compressing Digital Data in Digital Tables

Compress the data in a digital table 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.

Understand how to build a digital table that can be compressed.

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.

Figure 6. Compressed Data of a Digital Table shows two digital data tables, each displaying the same data.

  • The first table shows uncompressed digital data.
  • The second table shows the same digital data after compression.
