# How that a positive logic NAND gate is a negative logic NOR gate?

## How that a positive logic NAND gate is a negative logic NOR gate?

(Hint) To change a positive-logic gate to a negative-logic gate is to complement all inputs and output of the gate at the same time. A positive-logic NAND gate implements the function (xy)’. Hence a negative-logic NAND gate implements ((x’y’)’)’ = (x+y)’, which is NOR function.

**Is negative AND AND NAND gate are same?**

But the negative-OR which is nothing more than a NAND gate, we have a special case. When both inputs are LOW we get HIGH output, and when both inputs are HIGH we get LOW output. This is what differentiates a normal OR gate from a negative-OR gate.

### What is a negative NAND gate?

➢ A NAND gate can be used for an OR operation that requires one or more LOW inputs to produce a HIGH output. ➢ This aspect of NAND operation is referred to as negative-OR. The term negative in this context means that the inputs are defined to be in the active or asserted state when LOW.

**What is meant by negative logic?**

Negative Logic is a logical circuitry in which higher voltage level refers to LOW (‘0’ or FALSE) and Lower voltage level refers to HIGH(‘1’ or TRUE)

## What is positive and negative logic with example?

Positive logic is defined as a high voltage level representing a logic 1 and a low voltage level representing a logic 0. Negative logic is the reverse, i.e., a low voltage level represents a logic 1 and a high voltage level represents a logic 0.

**What is positive and negative logic give one example of each?**

Input and output polarity is indicated by a bubble or triangle. For example, the following shows a positive logic AND gate and a negative logic OR gate. But the system of digital logic where binary 0 represents higher voltage and binary 1 represents low voltage is called negative logic.

### Can a NAND gate function as negative OR gate?

A NAND gate can function as a negative-OR gate.

**What is a negative logic system?**

Negative Logic is a logical circuitry in which higher voltage level refers to LOW (‘0’ or FALSE) and Lower voltage level refers to HIGH(‘1’ or TRUE) View All Products.

## What is positive logic in a logic circuit?

Positive logic: If the signal that activates the logic gate has for its high (1) level a voltage more positive than for its low (0) level then the polarity of the logic is called positive logic, as shown in Fig. 10.21(a).
