Abstract
PURPOSE:To observe an output signal waveform in the still state, by setting the period ratio of two comparator output signals to an integral ratio and giving a trigger at a tme point when both output signals are turned on/off synchronously at every time of the least common multiple of their periods. CONSTITUTION:An oscillator I sets output signals (e') and (f') of comparators E and F and oscillates a signal at a period of the least common multiple of periods of both signals, and the output signal of the oscillator I is inputted to frequency dividers J, K, and L. The period of the frequency divider L is set to the least common multiple of periods of output signals (e') and (f') and generates a signal, which resets frequency dividers J and K, at every period of the least common multiple and inputs the signal to frequency dividers J and K. Frequency dividers J and K generate signals of prescribed periods respectively, and these signals are connected to -input terminals of comparators E and F through a saw- tooth wave signal generating and integrating circuit M or N connected in series to frequency dividers J and K.
