guys i've made a very simple zero crossing detector which gives a pluse on exact zero cross. i've simulated the ckt using multisim and it's perfectly runs. but when m going to implement the hardware m facing a problem with grounding.here m attaching d circuit and please tell me how can i make dat ground for both AC and DC. here the 5 v dc source is derived from the same AC source. And the AC voltage is directly fed through the secondary windings of step down tramsformer.
the output from the op-amp is square wave which is given to the xor gate directly and delayed which gives the pulse on Zero corssing.
