In this challenge you will be asked to build and minimize a combinational circuit using K-Map that outputs a signal when temperature is in a specific range.
Truth tables are not very useful for minimizing logic systems, and Boolean algebra has limited utility. Logic graphs offer the easiest and most useful pen-and-paper method of minimizing a logic system.
Situations can arise where a circuit has N input signals, but not all 2N combinations of inputs are possible. Or, if all 2N combinations of inputs are possible, some combinations might be irrelevant.
Entered variable maps simplify the process further by visually minimizing a K-map. The compression of the map makes a multi-variable system much easier to visualize and minimize.
