>What we need is a book that does the following: Break down REAL circuits from the wild, explain each module in isolation, then explain how it fits into the larger system.

Exactly! As an example, textbooks give the schematic for RC/RL/LC/RLC circuits and their functionality in a isolated manner. But in a real-world product they are amongst a whole other mass of modules and probably drawn badly in a schematic. How do i identify these combinations, infer their input/output and make sense of the overall PCB functionality? I would imagine this knowledge would be most practical and useful in the real-world.
