Logic Devices

1. Have you heard of combinational logic? Name any basic combinational logic device.
2. Can you name two main features of such devices?
3. How would you classify a ROM? Is it a combinational logic device or a sequential logic device?
4. Why do we classify a ROM as a combinational device when it has memory characteristics?
5. What is the most basic building block of combinational digital logic?
6. Let us say we want a NOT function using any of the single 2-input logic gates. How many ways can you think of for doing this?
7. What is the basic building block of a sequential logic device?
8. Sequential logic circuits use only sequential logic devices just as combinational logic circuits use only combinational logic devices. What do you have to say ...
