Abstract

PURPOSE: To obtain one digital output signal by making a comparison (n) times with regard to one digital input signal by using a digital comparator and a memory circuit stored with digital values of division points determined according to the inverse function of a transform function.
CONSTITUTION: Memory circuit 2 is stored with the inverse function of an aimed transform function between the maximum and minimum values of a digital input signal, e.g. digital values divided by 16 according to an exponential when the aimed transform function is a logarithmic function. Digital input signal IN is compared by digital comparator 4 to a digital value (the intermediate point is denoted as I hereafter because of division by 16.) outputted from memory circuit 2 and [1] when I is smaller or [0] when greater is outputted to shift register 5. On arrival of the 1st input signal, control circuit 3 clears shift register 5 and also assigns the address for reading division point I.
