WebOct 21, 2024 · You can identify noise through a spectral noise-density curve in microvolts per square-root hertz, and as integrated output noise in root-mean-square microvolts, typically over a specific range from 100 Hz to 100 kHz. Noise in the power supply can degrade the analog-to-digital converter’s performance and introduce clock jitter. matthew monahan new zealand
