A THD measurement can be made by applying a sine wave as an input to a system, and measuring the total energy which appears at the output of the system at harmonics of the input frequency. A sinusoidal input is used because sinusoids contain energy at only a single frequency; output energy that appears at any other frequency is thus the result of nonlinearities or time …

The ratio between the output signal level and the input signal level is the THD+N measurement. In PC audio, this is usually expressed as a dB ratio. Frequency response is a measure of the flatness...

I’ve done some THD measurements on my breadboard 6SN7 - 6SN7 - EL34PP project. THD measures 0,39% with 36 Watt output. Now my signal generator has 0,10% THD for 0,32 Volt PP input.

In audio electronics, the Total Harmonic Distortion (THD) is one of the most fundamental measurements. This project aims at designing a circuit that can be used as a rough THD measurement at the frequencies 1kHz and 20kHz. These frequencies are often used when measuring and comparing performance. Specifications.

In audio engineering, phase measurements are used to describe the positive or negative time offset in a cycle of a periodic waveform (such as a sine wave), measured from a reference waveform. The reference is usually the same signal at a different point in the system, or a related signal in a different channel in the system.
