Abstract
A digital data processing circuit has an inverting circuit for inverting a positive/negative sign of the output data of an encoding circuit. A correcting circuit returns the inverted sign of the data to an original sign of data after decoding. Offset is made for truncation noises caused by the respective filtering operations in the encoding circuit and said decoding circuit. Sound quality is suppressed from degrading without increasing the circuit scale.
