This application note presents a total harmonic distortion (THD) test circuit that uses active noise amplification to eliminate the need for expensive and often ineffective external filters. Abstract: ...

A critical measure for all audio components is distortion, typically specified as total harmonic distortion (THD) or total harmonic distortion + noise (THD+N). THD is defined as: ... THD+N is the rms ...

Total harmonic distortion (THD), is a popular measure of nonlinearity of a device. Learn about the considerable flexibility in defining THD while providing a relatively simple way to orchestrate all ...

The author is technical publications manager and a senior technical writer at Audio Precision in Beaverton, Ore. When reduced to its basics, the process of audio test and measurement is concerned with ...

Multilayer ceramic capacitors (MLCCs) are used extensively in modern electronics because they offer high volumetric efficiencies and low equivalent series resistances at attractive prices. These ...

Pioneer Electric&Research has introduced a hardened digital multimeter featuring total harmonic distortion measuring on AC voltages. The Model PDM-550 has been designed for flight-line maintenance ...
