    Gate Logic
AI Thread Summary
XNOR gate logic can be generalized for more than two inputs, functioning as an even function of 1's, meaning it outputs 1 when there is an even number of 1 inputs. The relationship can be expressed as NOT(A XOR B XOR C XOR D), indicating that the order of inputs does not affect the output. The confusion arises from interpreting the logic in terms of 0's, but the correct focus is on the parity of 1's. This clarification helps in understanding the behavior of XNOR gates in multi-input scenarios. Overall, XNOR gates maintain their logical properties regardless of the number of inputs.

hi,,
i m a bit confused in XNOR gate logic for MORE THAN 2 INPUTS..
is this logic correct "even function of 0's"..
need help in this regard,thanks in advance.. :confused:

I don't think they found the right answer there.

The generalization of an XOR gate is the Parity - it is 1 if there is an odd number of "1" inputs.
XNOR is an inversed XOR - it is 1 if there is an even number of "1" inputs.

It can be written as NOT(A XOR B XOR C XOR D) - and as interesting feature, the order of operations (and inputs) does not matter.
 
so it is even function of 1's... ??

Thread 'I need a concave mirror with a focal length length of 150 feet?'

I need to cut down a 3 year old dead tree from top down so tree causes no damage with small pieces falling. I need a mirror with a focal length of 150 ft. 12" diameter to 36" diameter will work good but I can't think of any easy way to build it. Nothing like this for sale on Ebay. I have a 30" Fresnel lens that I use to burn stumps it works great. Tree service wants $2000.

Thread 'Questions about the Tesla turbine'

Hi all, i have some questions about the tesla turbine: is a tesla turbine more efficient than a steam engine or a stirling engine ? about the discs of the tesla turbine warping because of the high speed rotations; does running the engine on a lower speed solve that or will the discs warp anyway after time ? what is the difference in efficiency between the tesla turbine running at high speed and running it at a lower speed ( as fast as possible but low enough to not warp de discs) and: i...

Thread 'Where is my curb stop?'

My water meter is submerged under water for about 95% of the year. Today I took a photograph of the inside of my water meter box because today is one of the rare days that my water meter is not submerged in water. Here is the photograph that I took of my water meter with the cover on: Here is a photograph I took of my water meter with the cover off: I edited the photograph to draw a red circle around a knob on my water meter. Is that knob that I drew a red circle around my meter...
