What is the process of logic circuits in producing an output?

In summary, the conversation discusses the functioning of logic gates, specifically the OR gate, and how it is able to output a 1 when given inputs of 1 and 0. The summary explains that logic gates work with voltage, with 1 representing a high voltage and 0 representing a low voltage. The implementation of electronic logic gates is also mentioned and a link to a Wikipedia article is provided for further information. The conversation ends with the acknowledgement of two different pages with gate implementations linked in the thread.

I know that if 1 and 0 goes through an OR gate, it gives 1. But how does the 1 come? how it works?
thanks

Usually, logic gates work with voltage - 1 is represented by a high voltage, 0 as low voltage. For the implementation of electronic logic gates, see the various Wikipedia articles, like this one.

yeah I know that they work with logic gates. But the problem is how does an OR gate know to output 1, if 1 and 0 was given as outputs

The most basic logic gates can be created with transistors wired up in various different ways.

That is explained in the link I posted.
Now you have two different pages with gate implementations linked in this thread.

1. How do logic circuits process information?

Logic circuits process information through the use of binary inputs (0s and 1s) which are then manipulated through logical operations such as AND, OR, and NOT gates. These operations allow for the circuit to make decisions and produce specific outputs based on the inputs received.

2. What are the basic components of a logic circuit?

The basic components of a logic circuit include logic gates, which are the building blocks of the circuit, and interconnections, which allow for the flow of information between the gates. Other components may include power sources and output indicators.

3. Can logic circuits perform complex operations?

Yes, logic circuits can perform complex operations through the use of multiple logic gates and interconnections. By combining different types of logic gates, circuits can be designed to perform a variety of tasks, from simple arithmetic operations to complex decision-making processes.

4. How do logic circuits store and retrieve information?

Logic circuits do not store information in the same way as a computer's memory. Instead, they use temporary storage elements such as flip-flops or latches to hold onto the data until it is needed. These elements can be triggered by clock signals to either store or release the information.

5. What is the difference between a combinational and sequential logic circuit?

A combinational logic circuit processes inputs and produces outputs based solely on the current state of the inputs. In contrast, a sequential logic circuit also takes into account the previous state of the inputs to determine its output. This allows for more complex operations and decision-making processes to be performed.
