Last Set of Combinational Notes

Two-bit comparator

The one above is a single compator

For a two-bit one, inputs would be AB CD, and compare it through LT, EQ, GT(less than, equal to, greater than) of AB > = < CD

Decoders:

A logic block that takes in an n-bit operator

Multiplexors

A logic block that takes in n inputs and selects one to be the output

  could also be called as a selector
