What is the significance of noise margin?

Noise margin is closely related to the DC voltage characteristics. This parameter allows to determine the allowable noise voltage on the input of a gate so that the output will not be corrupted. The specification most commonly used to describe noise margin (or noise immunity) uses two parameters: the LOW noise margin, NML, and the HIGH noise margin, NMH.

How to Calculate High Noise Margin?

High Noise Margin calculator uses High Noise Margin = Minimum High Output Voltage-Minimum High Input Voltage to calculate the High Noise Margin, The HIGH Noise Margin formula is defined as the s the difference between the minimum HIGH output voltage of the driving gate and the minimum HIGH input voltage recognized by the receiving gate. High Noise Margin is denoted by N_h symbol.

How to calculate High Noise Margin using this online calculator? To use this online calculator for High Noise Margin, enter Minimum High Output Voltage (V_oh) & Minimum High Input Voltage (V_ih) and hit the calculate button. Here is how the High Noise Margin calculation can be explained with given input values -> 3 = 5.01-2.
