  • Parallel to serial converter
    Patent number: 4377806
    Abstract: A parallel to serial converter is described for recording channel applications, wherein a coded symbol comprising a plural number of bits is to be rotated or converted to a serial stream. The converter includes a variable delay section which accepts the parallel code inputs on a plurality of lines and delays each input bit a predetermined number of counts, depending upon which line it is input on. The delay unit supplies a selector array of gates with bit signals, and the selector array reorders the bits into the desired serial stream. An output register is provided to reclock the serial stream prior to further channel processing.
