Abstract

PURPOSE:To simplify the constitution of an absolute value circuit with a reduction of cost, by combining the positive and negative polarity half-wave linear detecting circuits together. CONSTITUTION:The input signal fed to an input terminal 11 has the positive polarity and is accordingly amplified by an inverting amplifier 12 after passing through the resistances R7 and R8 to be turned into the negative polar at the output terminal of the amplifier 12. As a result, the diodes D4 and D3 are turned off and on respectively, and an end of the resistor R8 at the side connected to the amplifier 12 is equivalently earthed. In case the input signal is negative polar, this signal is amplified by the amplifier 12 after passing through the resistances R7 and R8 and turned into a signal of positive polarity at the output terminal of the amplifier 12. Accordingly the diodes D3 and D4 are turned off and on respectively, and no voltage is generated across the resistance R8. Thus no output signal is obtained at the output terminal 13.
