Скачать или смотреть How Computers Really Tell 0 from 1: The Physics Behind Digital Logic

Computers don’t “see” zeros and ones as numbers.
They recognize them physically — through voltage.

But voltage is unstable in the real world.
Noise, interference, thermal jitter, imperfect wires… all of these can distort signals.

So how do computers avoid misinterpreting 0 as 1?

In this video, we break down the engineering that makes digital logic reliable:

🔹 Logic Levels
Why computers don’t rely on exact voltages but divide them into “high” and “low” regions.

🔹 Noise Margin
How systems tolerate interference without making errors.

🔹 Signal Integrity
Propagation delay, distortion, reflections, and why PCBs need careful design.

🔹 Schmitt Triggers
The circuit that “cleans” noisy or ambiguous signals.

🔹 Why Binary Wins
Why we don’t use ternary or quaternary logic despite seeming more efficient.

This is the hidden physics and engineering behind how computers distinguish 0 and 1 — the foundation of all digital systems.
