📄️ Logic Gates: The Foundation of Digital Electronics
Digital electronics works with binary signals — only two possible states:
📄️ Combinational and Sequential Circuits: Building Complexity from Simple Gates
Logic gates by themselves are simple. But when we combine them in structured ways, we get powerful systems that can calculate, remember, and make decisions over time.
📄️ Analog vs Digital Signals
Everything in electronics ultimately falls into analog or digital.
📄️ Logic Levels and Thresholds
In digital electronics, we don’t care about exact voltages.
📄️ Pull-up and Pull-down Resistors
Pull-up and pull-down resistors are small components with a big job.
