Abstract

PURPOSE:To correct an error excellently by substituting error data by mean- value data when the following data is correct, and by substituting it by the last correct data when the following data is also erroneous. CONSTITUTION:The continuation of an error is detected by an error flag FER to control a changeover switch 22. When data fetched in a shift register 21 has no error, this data is fetched in a shift register 24 through a terminal D to obtain output data DT. If the data fetched in the shift register 21 has an error and next data D0 has no error, a mean value from an arithmetic circuit 23 is fetched in the shift register 24 through the terminal D to obtain the output data DT and when the next data also has an error, the output data of the shift register 24 is fetched in the shift register 24 through a terminal E to obtain the output data DT.
