32 point group system "mmm" in Orthorhombic crystal Hello, I am trying to understand the mmm symmetry in a orthorhombic crystal. Looking from the diagram I know there are 5 diads which will give me 10 unique planes in the same form. But how do I know the exact planes that are in the form given...

Yeah we can have 4 inputs, but I am still not sure about you saying using the two level AND-OR logic. I know how to construct the different kind of gates from NAND gates now, just need a clear concept how to solve this problem.

Homework Statement Using NAND, AND OR, &/or NOR gates build a vote counting machine. It should light an LED when majority votes are true (or answer "yes"). Assume 4 input votes only. Homework Equations Boolean Logic The Attempt at a Solution So I know the solution in terms of...

So I was playing around with logarithmic & exponential amplifiers in my lab class. I was looking at the following equations: http://upload.wikimedia.org/math/7/7/6/77663157d5b97ceb2e3edac5f587a620.png and http://upload.wikimedia.org/math/b/3/c/b3c569c85552561e41dec916f6e8ebe8.png...
