THD, SNR to SINAD Converter

signal processing sinad snr thd distortion

This page provides a converter to calculate SINAD (Signal-to-Noise and Distortion Ratio) from THD (Total Harmonic Distortion) and SNR (Signal-to-Noise Ratio) values.

Inputs

Outputs

EXAMPLE:

  • INPUTS: SNR (dB) = 15, THD (dB) = 1
  • OUTPUT: SINAD (dB) = 0.83

Total Harmonic Distortion (THD)

THD represents the root mean square (RMS) value of distortion components present at the harmonics of the input frequency. This input frequency is the frequency of the sinewave used as the input signal.
