# How can you obtain OR gate using diodes?

## How can you obtain OR gate using diodes?

To realise OR gate, we will use a diode at every input of the OR gate. The anode part of diode is connected with input while the cathode part is joined together and a resistor, connected with the cathode is grounded. In our case, we have taken two inputs which can be seen in the circuit above.

### WHAT IS AND gate using diode?

It is called AND gate because AND means “to multiply”. There are two inputs and one output in an AND Gate. When both the inputs of the AND gate is HIGH, the output is HIGH. Whereas the output is LOW or Zero in all the other cases. The AND gate using diodes follow the same working principle.

How diodes are used in logic gates?

Diode logic gates use diodes to perform OR and AND logic functions as shown in the circuit diagram. Connection of the LED at the output is optional which simply displays the logical state of the output, i.e. the logic state of output is 0 or 1, if LED is off or on, respectively.

How does OR gate work?

An OR gate is a logic gate that performs logical OR operation. A logical OR operation has a high output (1) if one or both the inputs to the gate are high (1). If neither input is high, a low output (0) results. Just like an AND gate, an OR gate may have any number of input probes but only one output probe.

## What is AND gate operation?

An AND gate is a logic gate having two or more inputs and a single output. An AND gate operates on logical multiplication rules. In this gate, if either of the inputs is low (0), then the output is also low. If all of the inputs are high (1), then the output will also be high. Only we get 1 when 1 is multiplied by 1.

### What is AND explain gate?

The AND gate is a basic digital logic gate that implements logical conjunction (∧) from mathematical logic – it behaves according to the truth table above. A HIGH output (1) results only if all the inputs to the AND gate are HIGH (1). If none or not all inputs to the AND gate are HIGH, LOW output results.

How do you make an OR gate?

OR Gate Circuit from NAND Gate Circuit Basically, we tie together the inputs of each of the first 2 NAND gates. This makes the inputs common. We then take one jumper wire from each NAND gate, which will serve as the inputs to our OR gate. The output of these gates feed into a 3rd NAND gate.

What is the use of OR gate?

The function of an OR gate is to find the maximum between the inputs which are binary in nature. It is one of the basic gates used in Boolean algebra and electronic circuits like transistor-transistor logic, and complementary metal-oxide semiconductors make use of it.

## Where are gates used?

Logic gates are used in microcontrollers, microprocessors, electronic and electrical project circuits, and embedded system applications. The basic logic gates are categorized into seven types as AND, OR, XOR, NAND, NOR, XNOR, and NOT. These are the important digital devices, mainly based on the Boolean function.
