Traffic-light controller Karnaugh map

This Karnaugh map lays out a traffic-light controller output in Gray-code order, where adjacent cells differ by one variable. The ones form two four-cell regions, giving a clear visual basis for simplification. The heatmap representation makes the minterms legible at card size, but the group boundaries and final Boolean expression should be confirmed from the stated function. Use variable names that match the associated truth table so an engineer can trace each cell back to the controller inputs. Before sharing it, compare the chart with the source table and make the scope explicit. A clear date range, population and unit help another reader interpret the pattern correctly and decide whether follow-up analysis is needed.

요청 내용

“Create a 4-variable Karnaugh map for traffic-light controller output F(A,B,C,D) with minterms 0, 1, 4, 5, 10, 11, 14 and 15; use Gray-code AB rows and CD columns.”

그렇다면Change minterms 10 and 11 to 0.Rename A through D to controller input labels.

01Set the scope

Use one reporting period and one clear unit.

02Read the pattern

Identify the largest concentration or directional change.

03Check the source

Confirm the displayed values against the underlying data.

Use this heatmap when the stated values and labels are the information the reader needs to compare.

자주 묻는 질문

What does this heatmap show?

A heatmap uses colour to show the size of a value at the intersection of two categories. It helps readers spot concentrations, gaps and repeated patterns quickly.

How should I read this heatmap?

Choose a colour scale whose minimum and maximum match the data, and include cell labels when precise values matter to the decision.

Can I adapt this heatmap example?

Yes. Replace the title, labels and values with your own data, then check that the prompt still describes every important element in the chart.
