Digital logic design design mini project if any one have then please share some information just like in which we use And OR NOT gate

 

The AND OR NOT gate is used in the design of counters where you need to decode the present state to decide the function of an individual flip-flop on the next clock edge.

 

Ultimately, all logic circuits can be built using many of just one type of universal gate. Could be a NAND or a NOR gate. The inverting function in these gates is essential (can't be done with just AND or OR). From this one type of gate you can construct flip-flops, counters, micro-controllers, digital video decoders, or anything! Or you can use both types of gate. That's how all digital logic circuits are made!

What would you like to design?

 

Look here for a great project. Not quite a mini one..

But as asked above, you need to define your question a bit. What are you wanting to make?
