Digital Design #01 | Voltage to Bit to Logic

Instructor: Dr. Süleyman Burak ÇELİK

Welcome to the Digital Design series. In this first lesson, we connect a physical voltage signal to the digital abstraction: bit, logic 0/1, input thresholds, and noise margin. In this video: - Why digital logic still starts with analog voltage - How voltage becomes a bit - The meaning of LOW, HIGH, and undefined regions - Input thresholds `V_IL` and `V_IH` - A worked threshold/noise-margin example Topics: 00:00 Voltage → Bit → Logic 00:35 Digital abstraction 01:15 Input thresholds 02:10 Safe LOW, undefined, safe HIGH 03:05 Worked example 03:45 Summary Next lesson: binary, hexadecimal, and signed numbers. #DigitalDesign #LogicDesign #DigitalElectronics #Thresholds #NoiseMargin #AcEdumy #Engineering
