Can you please help me in understanding the concept of these circuits ? Specially the NOR circuit.. this is really confusing

watch the video lectures of neso academy on youtube.

NOR and NAND are universal gates so you can make any circuit from it. thats why in such questions they ask how many nand or nor gates are required to make the circuit.

first write the equation of the given circuit

then just try to convert the equation in terms of (xy)' or (x+y)' i.e. Not AND and Not OR forms and then count how many (xy)' or (x+y)' are there in the equation. This will be equal to the number of gates required.
