Power Quality Symptoms & Solutions e-book is is written from an electronics point of view, rather than a power engineering one. And in so doing, provides the bridge between theory and real life.

It’s very cool – partly because it looks neat, but also partly because it shows you something important about fractals. Optical video feedback is a well-known phenomenon. If →

Audiophiles seem to revel in minor controversies – vinyl vs CD’s, tubes versus solid state, capacitor, wires, magic dots… and negative feedback. At one extreme (“objectivists” and engineers), the position is that “feedback makes amplifiers perfect”. At the other extreme (“subjectivists”) usually claim that “feedback is a menacing succubus that sucks the life out of →

Are Star-Quad is well known in the audio industry as a good cable construction to use in demanding environments because its superior handling of EMI. And that reputation is based in science; the Canare document, for example, contains lots of claims which can be tested objectively, and all those claims are rooted in physics-based (reality-based) →
