Electrical Level

2019-07-10

Electrical LevelElectrical Level or logic voltage levels. In logic circuits, two voltages are commonly used to represent two logic states, but sometimes two currents are used to represent them. High and low thresholds are specified for each logic circuit. When below the low threshold, the signal is "low". When above the high threshold, the signal is "high". Intermediate levels are undefined, resulting in highly implementation-specific circuit behavior.
