Digitizing Pulse Duration Modulated (PDM) data at a rapid rate and presenting it in a suitable form for data reduction has been a problem of data reduction centers for some time. The Magnavox Series 200 Converter is designed to accept PDM data recorded on magnetic tape, automatically digitize it, and record the digital information on the magnetic tape in a form suitable for input to a digital computer or other data reduction equipment.
