What is Sigma Delta Σ Δ ADC?
Delta-sigma (ΔΣ; or sigma-delta, ΣΔ) modulation is a method for encoding analog signals into digital signals as found in an analog-to-digital converter (ADC).
What is the principal of delta-sigma modulation?
The goal of delta-sigma modulation is to achieve higher transmission efficiency by transmitting only the changes (delta) in value between consecutive samples, rather than the actual samples themselves. ADCs and digital-to-analog converters (DACs) both can use delta-sigma modulation.
What are advantages in Sigma Delta ADC?
Delta-Sigma ADCs Improve Measurement Performance
Delta-sigma ADCs implement oversampling, decimation filtering, and quantization noise shaping to achieve high resolution and excellent antialiasing filtering.
