Summary:PURPOSE:To obtain an output data having a property close to an original signal by operating alternatively a data before and after a data of low reliability and discriminating the tendency of the level of some data just before the low reliability data to a prescribed value so as to round off or cut off the result of operation alternately thereby generating a new data. CONSTITUTION:When an interpolation data as shown in D1 is obtained, an output of a D/A 28 is higher than the 0 level. This shows that data having a level larger than the 0 level are much more than the data having smaller level in the preceding output data group in a time T1 designated by a frequency-divided period 24. Since an output of a comparator 30 goes to ''1'' and an output of an inverter 32 goes to ''0'' in this case, the carry-in of a full adder circuit 16 is logical 0. Then when the data just before the D1 is 1110(2)(+6) and the data just after is 0111(2)(-1), an output of the full adder 16 is 10101(1) and the data outputted attended therewith is 1010(2)(+2) and the fraction component (the LSB of the output of the full adder circuit 16) is cut off.
