ANALOG CODE CONVERSION SYSTEM

摘要

A code conversion system converts analog input signals to multinary code output signals. A polarity detector and comparator determines the polarity of an input signal and compares the input signal with reference signals. The polarity detector and comparator provide a multinary code output signal in accordance with the polarity and comparison. An amplitude divider divides the input signal in amplitude in a determined manner into a determined number of divided portions of equal amplitude and positions the divided portions of the input signal adjacent each other to lengthen the time duration of the divided portions. An amplifier amplifies the output signal of the amplitude divider a number of times equal to the determined number of divided portions. A time delay prevents overlap of the signal at the output of the amplifier with the signal supplied to the input of the amplitude divider. The amplitude divider, the amplifier and the time delay are connected in series circuit arrangement in a closed loop between the input of the system and the input of the polarity detector and comparator.
