MAKING_SLOW_LOGIC_PULSES_AUDIBLE

Published:2009/7/1 2:18:00 Author:May | From:SeekIC

This circuit is useful for monitoring slow logic pulses as a keying monitor or digital clock alarm. The Schmitt trigger is connected as an oscillator. The trimpot controls the pitch of the output. When the input goes high, the circuit will oscillate.
