Audio Amplifier measurements. Post by vishaudio » Mon Jun 17, 2019 6:00 pm. Hi All I just started building some really nice class a diy amplifiers which to me sound fantastic. Now i really want to analyse the performance of them such as THD,SNR, check the frequency response and if there is any noise due to the psu or component choices ...
DISTORTION MEASUREMENT IN AUDIO AMPLIFIERS
https://renardson-audio.com/distortiontest.pdf
1.1 Requirements for the measurement of distortion in audio frequency power amplifiers. In an ideal audio frequency power amplifier the output signal voltage would be identical to the input signal voltage multiplied by a constant. The input impedance would be infinite so that there would be no loading effect on the
