The logic gates add up to six. The Ex-OR gate produces “1” at the output when either of the input is at logic 1. AND gate is used when both inputs are at logic 1. The adder truth table comprises of the additional column that caters for the summed output, carry output, and carry-in input (Ross & Sheldon 75). …

The two binary digit full adders are found as the standard IC packages as 74LS283 and 74LS83 which add up and generate a CARRY and SUM output.

Another very useful and a common combinational logic is that of one bit magnitude comparator. The comparator is comprised of the NOT, NOR, and AND logic gates. The logic gates compare the signals found in the input terminal and produce the output that depend on the input condition (Ross & Sheldon 75). For instance, despite adding and subtracting numbers, they are able to compare them and find if the value of A is smaller than, equal to, or greater than input B. The one bit magnitude comparator achieves this by using the above logic gates that use the mechanism of Boolean algebra. The one bit magnitude comparator comprises of the three terminals that act as the terminals. One is greater than A>B, equalityA=B, and less than A
