A PC’s serial port provides signal lines that you can use to read voltage levels of digital circuits. You can use the port to test digital TTL (transistor-to-transistor-logic)-level circuits. You just ...

In digital circuits, a logic level is one of a finite number of states that a signal can have. Logic levels are usually represented by the voltage difference between the signal and ground (or some ...

The panel industry is rapidly accelerating to higher resolution and a greater number of bits per colour. Breakthroughs in resolution and color are possible only when increasing the overall data rate ...

Abstract: This paper presents the fabrication and experimental characterization of a multi-voltage level switching circuit with 6 channels designed to interface low-voltage control signals with a high ...
