Summary

Description
English: Simple circuit performing delta-sigma modulation on an input 20 kHz sine wave s(t). An ideal op amp integrator using s(t) and p(t) produces ε(t), which can be quantized and sampled by an ideal D flip flop to produce a pulse density modulation result p(t), which used as negative feedback. Demodulation of p(t) is achieved by aother integrator (or low-pass filter).

Simple circuit performing [[delta-sigma modulation]] on an input sine, using an ideal [[op amp integrator]] and [[D flip flop]] to produce a [[pulse density modulation]] used as negative feedback. Demodulation is simply another integration.
