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

AI Thread Summary
Logic circuits produce outputs based on the voltage levels representing binary values, with high voltage indicating 1 and low voltage indicating 0. An OR gate outputs 1 when at least one of its inputs is 1, functioning through specific configurations of transistors. The operation of these gates is defined by their design and the arrangement of components, which determine how inputs are processed. Understanding the behavior of logic gates can be further explored through various online resources. The discussion emphasizes the fundamental principles of how logic gates interpret and respond to input signals.

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.

Thread 'Underwater piezoelectric sensor array receive sensitivity'

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...

Thread 'Following up on the recent thread about Earth Resistance measurements'

I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...

Thread 'Question about bonding ground and neutral'

I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
