WebCCDF provides better resolution than CDF for low probability signals, especially when log format is used for the y-axis. The VSA plots CCDF using units of percent (%) for the y-axis and power (dB) for the x-axis. Power on the x-axis is relative to the average signal power, so 0 dB is the average power of the signal.
