Abstract

PURPOSE:To detect a peak-to-peak value, even if an input changes at positive or negative region only, by using an A/D converter, latch circuits, comparators and a subtraction circuit. CONSTITUTION:Each instantaneous value of an input signald ei is sampled and converted into a digital signal at an A/D converter. A maximum and minimum value is set to latch circuits 1, 2 respectively as an initial value, and comparators 1, 2 compare the output of the A/D converter and the content of the latch circuits 1, 2. That is, when the output of the A/D converter is greater than the content of the latch circuit 1, the output is set to the latch circuit 1, and when smaller than the content of the latch circuit 2, it is set to the latch circuit 2. With this operation, the maximum value of the input signal is set to the latch circuit 1 and the minimum value is set to the latch circuit 2, and the difference of the two is outputted from the subtractor.
