Abstract
PURPOSE:To accurately perform offset compensation even at a time when an input signal is impressed, by storing the value of a correct offset compensation voltage at the time of inputting no signal in a memory means, and performing the offset compensation based on the correct offset compensation voltage at the time of impressing the input signal. CONSTITUTION:At the time of inputting no signal, a switching means 6 is connected to contact (a) side, and the correct compensation voltage obtained from an integrator 3 is fed back via a filter 4, and the offset compensation is applied on a circuit system, and simultaneously, an offset correction voltage is supplied to the memory means 5, and stored in the means. At the time of impressing the input signal, the switching means 6 is switched to contact (b) side, and the correct offset compensation voltage at the time of inputting no signal stored in the memory means 5 is fed back via the filter 4, then, the offset compensation is applied on the circuit system. In such a way, it is possible to perform the offset compensation always based on the correct offset compensation voltage even at the time of impressing the input signal such as a music signal, etc.
