ABSTRACT:
A pulse generating apparatus which generates rectangular wave signal by opening and closing of a mechanical contact and has a differentiation circuit to output such pulse signal as corresponding to the rising position of said signal. Said apparatus has a rectangular wave generating means to generate rectangular wave signal by opening and closing a mechanical contact, a differentiation circuit to receive the rectangular wave signal from said rectangular wave generating means and to differentiate the same, and a high impedance element connected to the discharge circuit within said differentiation circuit. By this the discharging time constant factor of the differentiation circuit becomes large, sharply reducing the chattering pulse which parasitises to the rectangular wave signal.
