Abstract : A bi-phase signal detection apparatus having a multi-tapped delay line to delay a coded input signal. A polarity change in the input signal loads the signal on each delay tap into a parallel shift register. A subsequent delayed polarity change will apply the shift register signals into the decode logic circuit which determines the output signals.
