AI Thread Summary
A digital circuit can achieve interrupt-driven behavior using a simple XOR gate. The design requires two inputs and one output, where the output changes whenever either input changes value. The assumption is that the inputs will not change simultaneously, allowing for negligible circuit response time. The XOR gate effectively ensures that any transition in one input results in a corresponding transition in the output. This solution provides a straightforward method for achieving the desired functionality in digital circuits.

I'm much more of an analog guy myself, so I'm wondering if you guys can help me out. I am looking to design a digital circuit which takes two inputs, and has one output.

I want the following behavior:
Whenever either of the two inputs changes value, the output changes value. Assume that the two outputs never change at the same time, and that there is enough time between changes that any circuit response time is negligible.

Does anyone have any idea how this can be accomplished?

Okay, I am a bit chagrined to admit I was stumped for a while before posting, but I just figured it out. I can use a simple XOR gate - any transition in a single input results in a transition of the output.
 

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 'Electromagnet magnetic field issue'

Hi Guys We are a bunch a mechanical engineers trying to build a simple electromagnet. Our design is based on a very similar magnet. However, our version is about 10 times less magnetic and we are wondering why. Our coil has exactly same length, same number of layers and turns. What is possibly wrong? PIN and bracket are made of iron and are in electrical contact, exactly like the reference design. Any help will be appreciated. Thanks. edit: even same wire diameter and coil was wounded by a...

Thread 'Beauty of old electrical and measuring things, etc.'

Even as a kid, I saw beauty in old devices. That made me want to understand how they worked. I had lots of old things that I keep and now reviving. Old things need to work to see the beauty. Here's what I've done so far. Two views of the gadgets shelves and my small work space: Here's a close up look at the meters, gauges and other measuring things: This is what I think of as surface-mount electrical components and wiring. The components are very old and shows how...
