Can any digital circuit be built using only NAND or only NOR gates?
In the field of digital electronic circuits, this implies that it is possible to implement any Boolean function using just NAND gates. A similar case applies to the NOR function, and this is referred to as NOR logic.
Why do we build our integrated circuits IC’s using only NAND gates?
The NAND gate is significant because any boolean function can be implemented by using a combination of NAND gates. This property is called functional completeness. NAND gates with two or more inputs are available as integrated circuits in transistor-transistor logic, CMOS, and other logic families.
Why is NAND and NOR universal gates?
The NAND & NOR gates are called universal gates because they perform all the logical operations of basis gates like AND, OR, NOT. Answer: NOR AS AND An AND gate gives a 1 output when both inputs are 1; a NOR gate gives a 1 output only when both inputs are 0.
Why are NAND and NOR gates cheaper?
In most applications, NAND gates and NOR gates are the most commonly used, because they use less transistors internally than other types of gates do, which makes them cheaper to produce and buy. Also, NAND gates can actually be used to build any type of Boolean operator we need.
Why NAND gate and NOR gates are called as universal gate *?
∴ NAND and NOR gates are called universal gates because they can be combined to produce any of the other gates like OR, AND, and NOT gates.
HOW AND gate is made using NOR gate?
An AND gate gives a 1 output when both inputs are 1. Therefore, an AND gate is made by inverting the inputs of a NOR gate. Again, note that a NOT gate is equivalent to a NOR with its inputs joined….AND.
| Input A | Input B | Output Q |
|---|---|---|
| 0 | 1 | 0 |
| 1 | 0 | 0 |
| 1 | 1 | 1 |
