摘要： A distortion eliminating circuit includes an amplifier and a difference detector for detecting a difference between two signals. In this case, the input signal to the amplifier and the output signal therefrom, at least one of which is adjusted in level are applied to the difference detector, or the amplifier is made of a push-pull amplifier consisting of transistors opposite in conductivity type and a series connection of resistors is connected in parallel to a series connection of the emitter resistors of the push-pull amplifier to apply the output obtained at the connection point of the series connection of the resistors to the difference detector which is supplied with the input signal to the push-pull amplifier, and the output from the difference detector is added to the output from the amplifier, to thereby eliminate the distortion of the amplifier.
