-Last circuit is to see an precision Half wave rectifier with capacitor (Or without any capacitor if we use just 2th switch on 10k Resistor ) on first AO and with an capacitor on last AO (3th), the 2th AO is used to inverting the signal and see much better how it work; We don t use the same capacitor in same time (is an experiment to se how work an capacitor if we use directly on firsta AO or if we use on another AO, witch one is better etc) => Peak detect with AO
