Question about analog design: how well can projects be transferred amongst engineers? Is the knowledge base relatively similar across individuals, or is it hard for others to modify designs?
Electronics engineering (all engineering as far as possible really) does have a good amount of modularity. So understanding a circuit is about understanding each module, or simply being told their general function. You have a general geometry e.g. a balun or an antenna should follow, but the details very much follow from complex electromagnetic interactions, and I assume are designed through a intuition, simulation and testing loop. So if another engineer needs to slightly modify your design, he will usually just try adding or modifying individual modules to get the desired function -- that could include modifying the geometry of a circuit board analog filter, re-shaping an antenna for different directivity characteristics, etc.
