Document Summary

Made from an interconnection of logic gates. Reacts to values of signals at inputs to produced wanted output signal. Input and outputs variables are physically analog signal whose values are interpreted to be binary signal that represents logic 1 and logic 0. ** if registers are in circuit, then its a sequential circuit. For every n input variable, there are 2^n possible combinations of binary inputs. Given the logic diagram with boolean functions, truth table, or explanation of circuit: make sure given circuit is combinational (meaning no feedback paths or memory elements) Feedback path: connection from output of one gate to input of second gate whose output forms part of input to first gate. Design procedure: determine required number of inputs and outputs, derive truth table, find simplified boolean functions, draw logic diagram and verify correctness. Addition of three bits (two bits and a carry) Two half adders make a full adder.
