A new book authored by Robert N. Buono delves deeply into Class-D amplifiers, a crucial technology in audio designs. Buono ...

Most audiophiles and enthusiasts have grown up with at least a basic understanding of what an amplifier does. It takes a tiny alternating electrical signal that represents the moment-to-moment ...

A Zobel is an impedance matching circuit often used with loudspeakers. A Zobel circuit is also known as a Boucherot cell or somewhat incorrectly as an RC snubber. The nominal impedance of a ...

Class D amps are simple – just take an input, and use that to modulate a square wave with PWM. Send this PWM signal to a MOSFET or something, and you have the simplest class D amp in existence.

One of my first jobs as an engineer was at Empire Scientific Corp. in Garden City, NY in 1972. This was a high-end audio company that made speakers, turntables and phonograph cartridges. We had some ...

Technology has democratized the music industry in many obvious ways – notice how every band, regardless of stature, has a MySpace page? But one of technology's more subtle effects has been to make our ...
