noise margin

Englisch - Englisch

Definition von noise margin im Englisch Englisch wörterbuch: (Elektrik, Elektronik) In communications system engineering, noise margin is the ratio by which the signal exceeds the minimum acceptable amount. It is normally measured in decibels; (Elektrik, Elektronik) 2 volts, with anything below 0.2 volts considered a '0', and anything above 1.0 volts considered a '1'; (Elektrik, Elektronik) In a digital circuit, the noise margin is the amount by which the signal exceeds the threshold for a proper '0' or '1'; (Elektrik, Elektronik) In electrical engineering, noise margin is the amount by which a signal exceeds the minimum amount for proper operation. It is commonly used in at least two contexts:; (Elektrik, Elektronik) volts, and the noise margin for a '1' would be the amount by which a signal exceeds 1.0 volt. In this case noise margins are measured as an absolute voltage, not a ratio
