Analog digital modulator has converter to evaluate error signals and adder to add quantized and error signals

摘要

An analog/digital modulator quantizes a difference signal (d) between an analog input (x) and feedback (y). An A/D converter (7) evaluates error signals and with an adding unit (11) gives a digital output signal corresponding to the analog input. An analog/digital modulator comprises a forwards path with a device (2) to quantize a difference signal (d) between an analog input (x) and a feedback (y). An evaluation path with an A/D converter (7) evaluates error signals (d,y') and an adding unit (11) adds the signal (y) to an error signal to give a digital output signal (y(gen)) corresponding to the analog input.
