ABSTRACT:
In a recording/reproducing apparatus, having an analog-to-digital converter used in a recording mode and a digital-to-analog converter used in a reproducing mode; a digital filter comprises memories for storing first and second multiplication coefficient groups which provide predetermined filter characteristics and are in interpolated relation to each other; and, in the recording mode for first-and second-channel signals, the first and second multiplication coefficient groups are used for the first-and second-channel signals, respectively, and, in the reproducing mode, the second-and first-multiplication coefficient groups are used for the first-and second-channel signals, respectively. In recording and reproducing modes for a single-channel signal, the first and second multiplication coefficient groups are alternately used for successive samplings.
