What is noise immunity?

Some articles on noise immunity, noise:

Differential Pair - Advantages - Suitability For Use With Low-voltage Electronics
... causes problems with signaling because it reduces the noise immunity ... signaling helps to reduce these problems because, for a given supply voltage, it gives twice the noise immunity of a single-ended system ... Supposing that the voltage noise on one wire is uncorrelated to the noise on the other one, the result is that it takes twice as much noise to cause an error with the ...
Schmitt Trigger - Applications - Noise Immunity
... One application of a Schmitt trigger is to increase the noise immunity in a circuit with only a single input threshold ... threshold could cause the output to switch rapidly back and forth from noise alone ... Whereas the photodiode is prone to spurious switching due to noise from the environment, the delay added by the filter and Schmitt trigger ensures that the output only ...

Famous quotes containing the words immunity and/or noise:

    “There is immunity in reading, immunity in formal society, in office routine, in the company of old friends and in the giving of officious help to strangers, but there is no sanctuary in one bed from the memory of another. The past with its anguish will break through every defence-line of custom and habit; we must sleep and therefore we must dream.”
    —Cyril Connolly (1903–1974)

    “With the noise of the mourning of the Swattish nation!
    Fallen is at length
    Its tower of strength;
    Its sun is dimmed ere it had nooned;
    Dead lies the great Ahkoond,
    The great Ahkoond of Swat
    Is not!”
    —George Thomas Lanigan (1845–1886)
