What is the Delta Sigma method?
The Delta-Sigma (∆Σ or Sigma-Delta) method is a powerful technique, primarily used in Analog-to-Digital Converters (ADCs), that achieves high resolution by oversampling an analog signal, using a simple 1-bit quantizer with feedback, and then applying digital filtering (decimation) to average the oversampled data and shape quantization noise out of the desired signal band. It essentially converts an analog signal into a high-speed, low-resolution bitstream (like 1s and 0s) and uses digital processing to reconstruct it into a precise, high-resolution digital value, making it cost-effective and ideal for applications needing high accuracy like audio, process control, and precision measurements.How does delta-sigma work?
