The web is filled with introductions to Delta Sigma modulation (also sometimes referred to as Sigma Delta modulation) in the context of Delta Sigma converters. Unfortunately, the ones I’ve looked at ...

One popular way to reconstruct analog signals in microcontrollers (µCs) is through pulse width modulation (PWM). However, this modulation produces a large number of harmonic components, which limits ...

Sometimes, when an audio component dies, the root cause is something electrical. Other times, the issue instead ends up being fundamentally mechanical. Delta sigma modulation-based digital-to-analog ...

Based on the amount of e-mail I received after Part 3 of this series (Nov. 7, 2008, p. 18; www.electronicdesign.com, ED Online 19948), many of you have already guessed that an incremental integrator ...

Synchronous detection is a measurement method where a stimulus is modulated with some frequency and the response is demodulated to bring the signal back down to base band. Performed when a dc stimulus ...

For the latest generation of its iconic SL-1200 turntable, Technics engineers have tapped into the brand's digital amplifiers to develop a "revolutionary" new control method aimed at improving analog ...
