Question

What differences would you expect in filter performance on your prototype board vs. a real printed circuit board (PCB)? Why?

Answer 1

Difference basis	Prototype Board	Real PCB	Reason for Difference
Accuracy and Precision	Here the sole purpose is to make a working demonstration to show that designed filter meet working targets . So Accuracy is fair but filter is not so Precise.	Here actual accuracy and precision both are kept high	It is so because Prototype is just to show working idea of filter but PCB is there for actual implementation of filter design with real systems
Frequency Response Characteristics	It is Not So Sharp or there can be significant variation in Cutoff frequency of filter	It is Sharply defined and cutoff frequency is also with in precise tolerance	Because Frequency Response and filter equations are more accurately implemented in PCB design
Heat Loss and skin effect issue at higher frequency filters	More	Less	Since actual PCB uses rated components to suit the required application
