    摘要: A digital data demodulator which can reduce a loss of decodable digital data, and increase capability of reproducing digital data inputted through a transmission line even when an error occurs in the transmission line. In the digital data demodulator, a specific pattern detector (113) detects a specific pattern to be included in a modulation code, from a bit string inputted through a transmission line (104). A modulation code identifying unit (117) generates a demodulation data strobe signal (119) according to a phase of the modulation code including the specific pattern. An error corrector (121) samples demodulation data (109) in response to the demodulation data strobe signal (119) and reproduces the data to the original digital data.

    摘要: A voice recording/reproducing apparatus in accordance with the present invention includes a recording medium, a recording unit, a playback unit, and a reproduction manipulating unit. The recording unit records by voice the items of a schedule for each day on the recording medium. The playback unit reproduces by voice the items of a schedule for each day which are recorded on the recording medium. The playback manipulating unit is used to designate a day of a year for which a schedule must be played back, and to instruct the playback unit to play back the items of the schedule for the designated day. The recording unit can record a plurality of schedule items as the items of a schedule for each day. All the schedule items for the designated day are played back responsive to one manipulation performed on the playback manipulating unit.
