Abstract

PURPOSE:To execute exact off-set compensation in the same way at the time of no-signal input even at the time of an input signal impressing by storing the value of a proper off-set correcting voltage at the time of the no-signal input to a memory means and compensating an off-set based on the off-set correcting voltage stored at the time of the input signal impressing of a music signal, etc. CONSTITUTION:At the time of the no-signal input, a switch means 6 is in a contact (a) side and the proper off-set correcting voltage obtained from an integrator 3 is fed-back through a filter 4. Then, the off-set compensation is executed. Simultaneously, the off-set correcting voltage from the integrator 3 at the time of the no-signal input is supplied to a memory means 5 and stored here. At the time of the input signal impressing, the switch means 6 is changed- over to a contact (b) side and the proper off-set correcting voltage at the time of the no-signal input stored to the memory means 5 is returned through the filter 4. Then, the off-set compensation of a circuit system is executed. Thus, the malfunction of an off-set compensating circuit, which is occurred since a type of instruments is not generated at a positive and negative equal probability, is prevented.
