PURPOSE:To obtain integrating result of high accuracy by carrying out the internal and external integration by a division quadrature method. CONSTITUTION:In order to correct the error the square division area and the actual area in the division quadrature method, the difference between the preceding operation and the present operation is made as a side and the square aread of the side SDELTAYi is inputted as an error correction signal to the adder AD2. The adder AD3 subtracts or adds the signal which is obtained by shifting the error correction signal underside by one bit with respect to the integrating result Yi-1+SSIGMADELTAYi to the portion where the adder AD2 transmits the signal and thereby the internal integration and the external integration being obtained. As a result of this, the multiplication of (Yi-1+SSIGMADELTAYi)+ or -(1/2).SDELTAYi and the independent variable DELTAX from DELTAZ memory MZ4 is operated. To the operation result the immediately before result Ri-1 is added and the obtained{(Yi-1+SSIGMADELTAYi)+ or -(1/2).SDELTAYi}DELTAX+Ri-1 is transmitted to the output circuit OZ. |
