6. QN:  Design the assigned circuit (based on class serial number) in SOP(AOI) and POS (OAI) circuit using only 2 input NAND gates for (AOI/SOP) and using 2 input NOR gates for (OAI/POS).

Calculate the no. of logical elements (2 i/p NAND /NOR gates ) required to construct the circuit. (Assigned circuit is 4-input OR gate)
