Abstract
PURPOSE: To detect the maximum turnover level at every half period of a fundamental frequency and to print out the measured value and the generaing point by dividing again the measure voltage, which is obtained by a voltage-dividing circuit connected directly to a pantagraph, and by using alternately two peak hold circuits.
