Voltage Parameters of Logic Gate:

There are 4 Voltage parameters defined for each logic gate.
Voh - The minimum output voltage that will be considered as logic '1'
Vol - The maximum output voltage that can be considered as logic '0'
Vih - The minimum input voltage that can be considered as logic '1'
Vil - The maximum input voltage that can be considered as logic '0'

What is noise margin:
The noise margin is the parameter which gives any idea about the noise immunity of the logic gate.
It shows how much noise the logic gate can tolerate without affecting its normal operation.

For the logic gates, two types of Noise Margin are defined:
Noise Margin (High) = Voh - Vih
Noise Margin (Low) = Vil - Vol

What is Fan-In and Fan-out ?
Fan-out : It is the maximum number of logic gates (load) that can be connected at the output of the logic gate.

High State Fan-out = IOH (max) / IIH
Low State Fan-out = IOL (max) / IIL

Fan-In: The number of inputs that can be handled by the logic gate.

In this video, all these different parameters of the logic gates are explained in detail.

This video will be helpful to all the students of science and engineering in understanding the Noise Margin and Fan-out of Logic Gate.
