Signal integrity, a Common card

The card carries these facts from its Wikipedia article.

• In digital electronics, a stream of binary values is represented by a voltage waveform.
• However, digital signals are fundamentally analog in nature, and all signals are subject to effects such as noise, distortion, and loss.
• Over short distances and at low bit rates, a simple conductor can transmit this with sufficient fidelity.

ATK comes from the length of the article and DEF from its quality, so this card hits with 70 and blocks with 50: each hit it takes is cut by 20 %.
