Capacitor changes AC to DC 1st Op Amp amplifies Signal 2nd Op Amp checks if signal is above 1 Volt. (set by potentiometer) If signal is large enough, Op Amp sends out Signal to charge capacitor (connected to NE 555, previous slide) 1 M +12 +12 1 V 50 K • .1 F 10 K 2 10 K 10 K - + 7 3 -12 6 + - 220 K 3 6 10 K 2 4 10 K 1 M
