PCM Signal processing circuit

摘要: A pulse code modulation signal processing circuit, for example, an audio recording and reproducing apparatus to be used with a video tape recorder wherein errors occurring in the modulated signals are detected by serially providing incoming data words connected shift registers which are, respectively, adapted store one word. The outputs of first third register added divided two this output is inverted second results compared reference determine or zero. indicates that there error zero no error. ones zeros from comparing circuit stored three bit timed receiving if occurs any interpolation utilized interpolate serial registers. When does not contain ones, but only zeros, then it known correct.
