What are logic levels in digital electronics

Logic levels of different standards are explained in this video. Logic levels in digital electronics refer to the distinct voltage values that represent binary states, typically 0 and 1, in a digital circuit. These levels indicate the presence or absence of an electrical signal, which in turn represents a specific logical value. In most digital systems, there are two main logic levels: Low Level (Logic 0): This corresponds to the absence of a significant voltage or a voltage that is interpreted as a logical "0." It is often referred to as "ground," "low," or "off." High Level (Logic 1): This corresponds to the presence of a significant voltage or a voltage that is interpreted as a logical "1." It is often referred to as "Vcc" (voltage supply), "high," or "on." The specific voltage values that correspond to these logic levels can vary depending on the technology being used (TTL, CMOS, etc.), the power supply voltage, and other factors. For example, in TTL (Transistor-Transistor Logic), a logic "0" is typically represented by a voltage close to 0 volts, while a logic "1" is represented by a voltage close to the supply voltage (e.g., 5 volts). In CMOS (Complementary Metal-Oxide-Semiconductor) logic, a logic "0" might be represented by a low voltage (close to 0 volts), and a logic "1" might be represented by a high voltage (close to the supply voltage). The distinction between these logic levels is crucial for proper communication and operation of digital circuits. Components like transistors and gates use these voltage levels to perform logical operations and make decisions based on the binary values they represent. The accurate interpretation of logic levels ensures that information is correctly processed and transmitted through digital systems. #logical #logiclevels #logicvoltage ‪@EasySkill‬ You can follow me on Facebook: https://www.facebook.com/profile.php?...
