2 bit comparator

00:35:11

If A=B only second last NOR will be high
If A>B only last NOR will be high
If A<B only bottom AND will be high

Top left inputs are Ao and Bo respectively
Middle left inputs are A1 and B1 respectively

Basically here i use the concept of subtraction rather than comparing corresponding bits.
