MAGNETIC TAPE READOUT SIGNAL PROCESSING SYSTEMS

摘要

A system is provided for processing the signals read out from a phase modulated recorded magnetic tape. From each track of the tape are derived two distinct series of digital value significant pulses in which nonsignificant pulses appear. The system provides for elimination of such nonsignificant pulses and rearrangement of the remaining pulses for temporary registration in a plural stage assembly elementary register. It further provides for detection of various defects resulting from dynamic and magnetic skew and casual reconstitution of mutilated characters.
