The Delta-Sigma Modulator is the core of the ADC and is responsible for digitizing the input analog signal while reducing noise through a couple of techniques, namely oversampling and noise shaping.

A technique that is used to sample voice waves and convert them into digital code. Delta modulation typically samples the wave 32,000 times per second, but generates only one bit per sample.

It then uses Sigma-Delta modulation to encode the analog signal into a binary bitstream. You should really try this out. The picture above is from when I was testing it out since it only took a ...
