This video is one of the important videos of this channel.
In this video, you will see Boolean algebra in logic gates.
These gates include "buffer - Not - and - or - Nand - nor - XOR - XNOR".
You will see these gates in Siemens PLC and with "Step-7" software.
Programming is in "LAD", "STL" and "FBD" languages.
The number of inputs may be one, two or three.
Some gates have 2 methods for programming.
I will prove Demorgan's Lows by "Nand" and "Nor" gates.
