“How can we have multiple inputs control a single output?”
Circuit technology can be found in all aspects of our lives nowadays, whether it be in the smartphones we carry or the airplanes that carry us. However, one problem that we keep on running into is how to take logic from multiple inputs and have it govern a single output. Well, if we can apply our engineering mindsets, then we can find that combining everything with sequential logic, we can invent a machine known as a multiplexer which can accomplish our goal. An example schematic of a multiplexer can be seen in the image above.
