Abstract
PURPOSE: To determined a binary code as a new peak value when a digital code is larger than the past maximum value by converting binary series data subjected to the pulse-code modulation into parallel and comparing the value thus obtained with the maximum peak value of the past data by means of a digital comparator.
CONSTITUTION: The series data converted into a digital code is impressed on a comparation input converted into parallel by shift registers 13, 14 and D-FF 15W17. Meanwhile, on the other comparation input is impressed a code held by D-FF 24W 26 corresponding to the past maximum peak value. The digital code obtained moment by moment is compared with the code of the past maximum peak value, and, when being larger than the past value, it is outputted from a comparator 22 by a rate corresponding to one pulse of a clock pulse 28 with the width synchronized with the clock pulse 28 for conversion into parallel. By the rise of this pulse, the parallel code of the D-FF 15W17 equivalent to a new peak value is hled by D-FF 24W26.
