Attached is a one-chip solution to the PCB Etching Tank problem. It will work for any logic combination of the three inputs, and it’s easy to go from the truth table to the circuit diagram. It uses a ...

Simulation hardware is a device that mimics the input and output signals of your ladder logic diagram. You can use simulation hardware to test your ladder logic diagram with real or simulated ...

Logic symbols for digital inputs and outputs are typically based on Boolean algebra, a system of logic using two values: true and false. The most common logic symbols include AND, OR, NOT, and XOR.

But wait! Let’s further suppose that, when we look around, we see our design employs only one of the two 4-input AND gates in a 74x21 package. In this case, we could coerce the unused 4-input AND to ...

We propose a method for computing maximal sets of symmetric inputs in logic circuits, using a test generation procedure for single stuck-at faults. The method is enhanced by a heuristic that can be ...

This paper concentrated on the path planning for autonomous underwater vehicle (AUV) to avoid collisions with the moving obstacles. Considering the influence of moving speed of the obstacles on ...
