Circuit arrangement for digitizing an information signal has amplifier circuit containing non-linear feedback amplifier and digitizing circuit in form of comparator

摘要

The arrangement has an amplifier circuit (1,3,5) for amplifying the information signal and a digitizing device for digitizing the amplified signal. The amplifier circuit contains a non-linear amplifier (5-7) and the digitizing circuit is a comparator. The non-linear amplifier is a feedback amplifier with a non-linear feedback element (6).
