: Sine waves (ranging from 20Hz to 20KHz), white noise, and pink noise for measuring frequency response, jitter, and signal-to-noise ratios.

Ensures that the RF signal is at its peak quality before it reaches the digital-to-analog converter (DAC). The Evolution of the Test CD: YEDS18 vs. Modern Tools

The Sony YEDS-18 is a factory-produced . Unlike a music CD, it does not contain songs. Instead, it contains a specific suite of digital signals, pink noise, and frequency sweeps.
