Title:
PROCESSOR OF MOVING AVERAGE
Document Type and Number:
Japanese Patent JPS60112177
Kind Code:
A
Abstract:
PURPOSE:To enable a device to have good trackability by detecting sudden changes in input data by comaring them with an output of moving average operation, and replacing prior-change data to post-change data among the input data. CONSTITUTION:Input data added to an input terminal IN enter a shift registor 2 through a sampling holding circuit 1. A comparator 9 compares inputted current data with an output of a moving average operation circuit 8, and judges whether or not the inputted data change suddenly. A comparator 10 judges whether or not the value sampled previously deviates from a moving average value. When both comparators 9 and 10 judge sudden changes in inputted data, they output the signal which switches respective changeover switches 23, 25 and 27 to the current value side. Thus, when inputted data change suddenly, the data inputted previous time, those inputted two times before and those inputted three times before can be switched to the current value; moving average processing with good trackability can be executed for sudden changes in inputted data.
