Summary
Description Simple Circuit for Delta-Sigma Modulation.svg |
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
).
