摘要: Noise rejection in an integrating type of analogue to digital converter is improved by effecting the integration accordance with a variable weighting function, preferably step function. Functions are described which flatten response versus frequency curve neighborhood zeroes and introduce more into this curve. The may be introduced scaling either on side or instrument.
