An integrated quantized signal smoothing processor samples an analog signal, converts it to a digital number and averages n samples, the averages of n equal or nearly equal signals will be quantized with the quantization interval of an A/D converter. An improvement signal is added at the input of the A/D converter with the output quantization interval becoming q/n. For a given accuracy, the improvement permits a lower number of bits in the A/D converter.
