Web26 Jun 2001 · THD is primarily even-order harmonic distortion, measured with single test tones. Even-order harmonic distortion up to around 2% during program material is almost always inaudible. Music and movie soundtracks are more complex, though, and the complex odd-order harmonic distortions are much more audible, even in miniscule amounts. Power amplifier circuits (output stages) are classified as A, B, AB and C for linear designs—and class D and E for switching designs. The classes are based on the proportion of each input cycle (conduction angle) during which an amplifying device passes current. The image of the conduction angle derives from amplifying a sinusoidal signal. If the device is always on, the conducting angle …
