I’m new to digital electronics and try to understand how logic gates works.
In books many times Zeroes and ones are referred as Low and High respectively, is Low and High used as an indication of lower input voltage and higher input voltage ?
And if Zero used as a low input voltage then isn’t no input can also be considered as Zero by default?
or it depends on how the gates are implemented (e.g – AND gate can be implemented using diodes or transistors) and so in some cases no input by default is same as Zero input while in others they are different ?
I’ll thankful if anyone can explain these things using an easy example !
