AI Thread Summary
In K-maps, "don't cares" (denoted as 'd') can be treated as either 1 or 0, depending on which option leads to a more simplified logic expression. When circling groups of 1s, including 'd' values can help create larger groups, thus optimizing the simplification process. The key is to strategically choose how to use 'd' to achieve the best outcome in the K-map. This flexibility allows for more efficient circuit design. Understanding the role of don't cares is crucial for effective logic minimization.

Question about don't cares in kmaps
in a 16 cell box
d 1 d 0
d 1 1 1
0 d 1 d
0 0 0 0
What do don't care stand for exactly? like when you do the circling of ones do you also include the D or you don't, even if the D are 1?

Thread 'Have I solved this structural engineering equation correctly?'
Hi all, I have a structural engineering book from 1979. I am trying to follow it as best as I can. I have come to a formula that calculates the rotations in radians at the rigid joint that requires an iterative procedure. This equation comes in the form of: $$ x_i = \frac {Q_ih_i + Q_{i+1}h_{i+1}}{4K} + \frac {C}{K}x_{i-1} + \frac {C}{K}x_{i+1} $$ Where: ## Q ## is the horizontal storey shear ## h ## is the storey height ## K = (6G_i + C_i + C_{i+1}) ## ## G = \frac {I_g}{h} ## ## C...
