Goals of the Lab (1) To understand the IC 74LS83 4-bit adder. (2) To design an arithmetic circuit using the 4-bit adder IC 74LS83. (3) To build and test the arithmetic circuit using laboratory hardware. Procedures Step 1: Familiarize yourself with the IC 74LS83 4-bit adder. Step 2: Construct and test the circuit designed in the previous lab using the 74LS83. The table below contains our test values and the resulting output.

This circuit was relatively easy to implement and works the same as the circuit designed in the previous lab. A key lesson learned is how much simpler integrated circuits such as "full adders" make hardware design....
