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

Click For Summary

Discussion Overview

The discussion revolves around the functioning of logic circuits, specifically focusing on how OR gates produce outputs based on input values of 1 and 0. The scope includes conceptual understanding and technical explanations related to electronic logic gates.

Discussion Character

  • Conceptual clarification, Technical explanation

Main Points Raised

  • One participant notes that an OR gate outputs 1 when given inputs of 1 and 0, expressing curiosity about the underlying mechanism of this output.
  • Another participant explains that logic gates operate using voltage levels, where 1 corresponds to high voltage and 0 to low voltage.
  • Several participants question how an OR gate determines its output based on the inputs, indicating a desire for deeper understanding of the logic behind the gate's operation.
  • One participant mentions that basic logic gates can be constructed using transistors arranged in various configurations, suggesting a link to further resources for understanding these implementations.
  • Another participant reiterates the question about the OR gate's output, pointing to previously shared resources for clarification.

Areas of Agreement / Disagreement

Participants express a shared interest in understanding the operation of OR gates, but there is no consensus on the explanation of how the output is determined from the inputs. Multiple viewpoints and questions remain unresolved.

Contextual Notes

The discussion highlights a lack of clarity regarding the mechanisms of logic gates, with participants relying on external resources for explanations. There are also repeated questions about the same concept, indicating potential gaps in understanding.

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.
 
Thanks
