Combinational Circuits A combinational circuit consists of input variables, output variables, and logic gates that transform binary information from the input data to the output.
A combinational circuit cannot have any storage elements (registers) or any feedback paths (connections from the output of one gate to the input of a second gate that directly or indirectly affects the input to the first gate).
As an example, consider the following combinational circuit with 3 inputs and 2 outputs (n = 3, m = 2): A B C A B C A B A C B C T2 F1 T1
If there are m..
