Abstract
PURPOSE:To keep the signal given to a distortion generating circuit constant regardless of the temperature change by providing a variable gain amplifier and a temperature compensation circuit controlling the gain of the variable gain amplifier in response to the temperature change to the pre-stage of the distortion generation circuit. CONSTITUTION:The variable gain amplifier 8 and the temperature compensation circuit A are provided on the pre-stage of a ternary distortion generator 5. The amplification factor is changed corresponding to the temperature change by the temperature compensation diode 12 provided on a DC amplifier 11. The amplifier 8 is subjected to feedback control by the amplified voltage. Automatic gain control is applied to the signal given to the generator 5. Then the input level of the generator 5 is changed against the change in the operating point due to the temperature change in the nonlinear element of the detector 10 and the generator 5 and the output ternary signal level of the generator 5 is kept constant.
