Abstract
A variable speed digital signal reproducing apparatus, particularly related to low speed reproduction of a digital signals recorded in a recording medium. The apparatus includes a unit for determining whether a reproduction PCM signal is renewed or not. Based on the renewal determination, PCM data of one frame is stored in a memory and the PCM data is read at a frequency rate corresponding to a tape reproducing speed at that time. Furthermore an interpolating device operates on the read PCM data to produce a PCM signal having the same frequency with which the PCM signal was read from the memory means.
