Summary

Description
English: US Patent #3192371: "Feedback Integrating System" figure 1 by Charles B Brahm. The components inside the dotted box #10 resemble an op-amp integrator. The analog-to-digtial and digital-to-analog converters appear to be 4-bit, using designations "S" for "sign bit", "1" for the least-significant bit, "2" for the next significant bit, and "4" for the next significant bit. The entire top half of the figure is (arguably) a delta-sigma modulator.
