The circuit uses a six-gate IC CD4069, and its Gate 1, Gate 2, 3, and R1, R2, R3 form a three-level signal amplifier. Once people click on a Palm, applause is picked up by electret microphone MIC, and its sensitivity is adjusted by RP and amplified by subsequent three-level amplifier, then detected by C5, D5, D6, C6 to get DC control voltage, this voltage is inverted by gate 4 to control the flip of subsequent bistable circuit.
