Interpreting a Block Diagram: How Should it be Read?

Click For Summary
SUMMARY

The discussion focuses on interpreting a block diagram related to Kalman filtering. It highlights the flow of signals, specifically the variable 'u' being modified by noise before entering the Kalman filter, and the variable 'y' being affected by sensor noise. The output 'ye' from the Kalman filter is derived from the processed input 'yv'. The conversation emphasizes the need for clarity in understanding how noise impacts these signals within the diagram.

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.
