The Distortion Magnifier
Audio equipment has become so transparent that it taxes the resolving power of all but the most expensive distortion analyzers. Bob Cordell developed the Distortion...
A low noise laboratory-grade measurement preamplifier
No lab or hobby shack should be without a preamplifier to measure very low signals with very low noise, defined gain and wide bandwidth. Samuel Groner's latest...
A Poor Man's Measurement Amplifier
Every audio designer finds himself eventually in the situation that he needs a very low noise preamplifier to interface between the tiny circuit signals and his test...

Every serious tube buff should have access to at least one...
Capacitor sound revisited - Distortion mechanisms behind the sound of Wound and Stacked Capacitors - Cyril Bateman
Cyril’s capacitor article series in Electronics World, a few decades ago, were a landmark in our understanding of the mechanisms behind capacitor dielectric...
Quadrature Bridge Measures Harmonic Distortion in Capacitors
This article considers the measurement of harmonic distortion in capacitors using a bridge circuit. Each arm of the bridge consist of one resistor and one capacitor....
An Open-Source Electroacoustic Measurement System: Part 1: Theory, Practicalities & Acoustic Examples; Part 2: Sound Card Setup, System Characterization and a few more Examples
This two-part article describes the design, configuration, software and use of a general-purpose electroacoustic measurement system. The system is based on typical...
