    Reduction
AI Thread Summary
The discussion focuses on the Boolean expression (\overline a \overline b \overline c)+(a \overline b \overline c)+(\overline a \overline b d) and whether it can be reduced. The original poster struggles to find a reduction and notes discrepancies when creating a truth table. Another participant suggests that \overline b \overline c+\overline a \overline b d might be the correct reduction. They also mention that Karnaugh maps (K-maps) are a helpful tool for simplifying Boolean expressions, especially for beginners. Overall, K-maps are recommended as an easier method compared to algebraic reduction.

(\overline a \overline b \overline c)+(a \overline b \overline c)+(\overline a \overline b d)
is this reducable?
I'm new to this as you may be able to tell, but I've went through this and have not found a way to reduce it, well I thought I had but then when I make a truth table the results don't match. Please help me out if you can, I'd greatly appreciate it.


edit: is \overline b \overline c+\overline a \overline b d the answer?

The answer looks right to me. Btw, K-maps are helpful for these problems.
 
yeah, thanks. We just learned about kmaps today in class as a matter of fact. seems much easier than trying to reduce through algebra lol
 

Thread 'How might electronics be different if AC voltage was 72V at 45 Hz?'

Hey guys. I have a question related to electricity and alternating current. Say an alien fictional society developed electricity, and settled on a standard like 73V AC current at 46 Hz. How would appliances be designed, and what impact would the lower frequency and voltage have on transformers, wiring, TVs, computers, LEDs, motors, and heating, assuming the laws of physics and technology are the same as on Earth?

Thread 'Why does the amperage go real high if there is a low voltage short?'

I used to be an HVAC technician. One time I had a service call in which there was no power to the thermostat. The thermostat did not have power because the fuse in the air handler was blown. The fuse in the air handler was blown because there was a low voltage short. The rubber coating on one of the thermostat wires was chewed off by a rodent. The exposed metal in the thermostat wire was touching the metal cabinet of the air handler. This was a low voltage short. This low voltage...

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...
