System function of an acoustic transmission system including an audio apparatus shows a complicated aspect in general. This paper describes the methods and the means for compensating these system function, a concrete example being shown. In the first place, the procedure for obtaining the transfer function of a compensation circuit is described. For realizing this transfer function, a statespace realization without integrators is used, which is constructed using systems theories. As an example of compensating system function, a loudspeaker system in free field is adopted and the procedure for constructing the compensation circuit is described in detail. After the utilization of the compensation circuit is confirmed, the problem on compensating system function is considered. According to circumstances, the frequency response of the compensation circuit is wanted to make variable. Thereupon, the compensation circuit which makes parameters in a transfer function variable is investigated. As the result, new original circuits are thought out from state-space realization without integrators.
