Abstract

The disclosed preset pulse generating device serves a digital system which is controlled by a clock pulse oscillating circuit and returned to the initial state by a reset pulse. It includes a first circuit which is charged to a predetermined level when the clock pulse oscillating circuit is operating, and a charge level detecting circuit for producing the reset pulse when the output of the first circuit falls below the predetermined level as the clock pulse oscillating circuit stops operating.
