Coefficient multipliers are inserted into feedback loops between an output of a delay unit and an input of an adder, and between an output of the other delay unit and the other input of the adder. Here, it is assumed that an input data supplied to an integration circuit is X(z), an output data supplied from the integration circuit is A(z), and an output data of a quantizer is Y(z). Then, the following equations are met.
