Electronic Gong Circuit


Posted on Apr 23, 2012

The electronic gong is comprised of an oscillator (built around half of a 74COON quad 2-input NAND gate), an active twin-T filter (built around a TL081), and will drive an audio amplifier IC such as aii LM386N. Pulses from astable multivibrator ICl cause the twin-tee active filter U2 to ring, producing a damped sinusoidal output.
