MHB Interpreting a Block Diagram: How Should it be Read?

AI Thread Summary
The discussion focuses on interpreting a block diagram related to Kalman filtering. It highlights the ambiguity in how input signals (u) are processed with noise, as the diagram does not specify whether the noise is added or subtracted. Additionally, the flow of output signals (y) from the plant is also affected by sensor noise before entering the Kalman filter. Participants express uncertainty about the correct interpretation of the diagram, particularly regarding the handling of noise. Overall, clarity in the representation of signal processing in block diagrams is essential for accurate understanding.

How do we interept what is going on in the block diagram?

We have u going in and being added or subtracted from noise but we arent giving the plus and minus to determine which it is. Then there is a branch off u going straight to the Kalman filter. Then y comes from the plant and is added or subtract to sensor noise and yv comes out and enters the Kalman filter with an output of ye. Additionally, we have a branch off y.

This is just from visualizing it but how should it be read?

Can't say I'm an expert on Kalman filtering, though I've heard of it. I would say, though, that both noises are added to the incoming signals.
 
Seemingly by some mathematical coincidence, a hexagon of sides 2,2,7,7, 11, and 11 can be inscribed in a circle of radius 7. The other day I saw a math problem on line, which they said came from a Polish Olympiad, where you compute the length x of the 3rd side which is the same as the radius, so that the sides of length 2,x, and 11 are inscribed on the arc of a semi-circle. The law of cosines applied twice gives the answer for x of exactly 7, but the arithmetic is so complex that the...
Is it possible to arrange six pencils such that each one touches the other five? If so, how? This is an adaption of a Martin Gardner puzzle only I changed it from cigarettes to pencils and left out the clues because PF folks don’t need clues. From the book “My Best Mathematical and Logic Puzzles”. Dover, 1994.
Thread 'Imaginary Pythagoras'
I posted this in the Lame Math thread, but it's got me thinking. Is there any validity to this? Or is it really just a mathematical trick? Naively, I see that i2 + plus 12 does equal zero2. But does this have a meaning? I know one can treat the imaginary number line as just another axis like the reals, but does that mean this does represent a triangle in the complex plane with a hypotenuse of length zero? Ibix offered a rendering of the diagram using what I assume is matrix* notation...
