Noise margins

Noise margins in digital electronics refer to the extra buffer or safety space between the minimum and maximum voltage levels that a device recognizes as a logical high (1) or low (0). They ensure that even if some electrical interference or "noise" affects the signal, it won't cause errors in interpreting the data. Essentially, noise margins provide a margin of error, helping digital circuits operate reliably by preventing false switching due to minor voltage fluctuations. This reliability is crucial in maintaining accurate data transmission and processing within electronic systems.
