DISTORTION MEASUREMENT IN AUDIO AMPLIFIERS
https://renardson-audio.com/distortiontest.pdf
1.2 Distortion specifications and measurement methods. It is convenient to specify the distortion of an amplifier in a form which enables comparison with other amplifiers or with some known standard requirement, e.g. the DIN 45 500 (Ref.5) standard …
A DIY approach to distortion measurements for audio amplifiers

A DIY approach to distortion measurements for audio amplifiers. Posted on 1 September 2019 11 November 2021. I imagine I am typical of many DIY audio enthusiasts in that I build something and hope that subjectively it sounds good. However, I am also curious about the objective measurements of the equipment.

THD Distortion Ratio vs Frequency - It's good housekeeping to sweep distortion vs frequency to see how the amplifier performs for the entire audio bandwidth instead of the typical discrete 1kHz single test tone. You may see us include these types of measurements in amplifier reviews or at least make reference to the fact that we did a ...
Distortion Measurement - Audio Amplifier Design

Distortion Measurement. I used a signal nulling method for most of the distortion measurements of my amplifier designs. This was the subject of my MSc dissertation in 1978, and I have sometimes been asked for more details, so here is the full original version: PDF file. The earliest published example of the method I have found appeared in ...

3. Sep 20, 2020. #1. I'd like to suggest that amirm use the same SMPTE IM distortion versus output level in his amplifier evaluations that he uses in his DAC evaluations. Measurement of harmonic distortion at 1KHZ reveals very little about an amplifier's quality of design or listenability, but the IM distortion measurement.
