Principles of Sigma-Delta ADCs Abstract: This article covers the theory behind a Delta-Sigma analog-to-digital converter (ADC). It specifically focuses on key digital concepts of oversampling‚ noise shaping‚ and decimation filtering. Introduction Sigma-delta converters offer high resolution‚ high integration‚ and low cost‚ making them a good ADC choice for applications such as process control and monitoring. The analog side of a sigma-delta converter (a 1-bit ADC) is very simple. The digital side

A Power Line Communication Explained (1984) Challenges and Technologies Abstract This paper reviews the sources of attenuation‚ noise and distortion encountered when communicating over AC power wiring. Various technologies which have been used to address these challenges‚ such as spread spectrum and digital signal processing‚ are then examined in light of the known channel conditions. Introduction While the idea of sending communication signals on the same pair of wires as are used for
