The Novosibirsk Laboratories in Siberia have developed a transistorised harmonic distortion measuring set. It is designed for the frequency range 50 to 15,000 c/s and the limits of percentage ...

One of the more common building blocks of a voltage controlled amplifier (VCA) is a differential pair amplifier. For a VCA configuration, the (top) two bases receive a control voltage for gain control ...

As we’ve traced our no-nonsense path through the world of Hi-Fi audio, we’ve started with the listener, understood the limitations of the human ear, and thence proceeded to the loudspeaker. We’ve ...

A new high-speed operational amplifier greatly minimizes voltage noise and harmonic distortion. The AD8099 features an advanced circuit architecture that enables it to deliver both 0.95 nV/rt Hz ...

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 ...

This is an excerpt from “Self on Audio,” by Douglas Self, used with permission from Newnes Publishers, a division of Elsevier. For many years I felt that the output stages of power amplifiers ...

We all know what distortion sounds like. We’ve heard it in heavy metal tunes, cheap iPod docks and the crummy speakers at Taco Bell drive-thrus. And we’ve all read distortion specs on things like ...
