This volume is one of a series designed specifically to teach electronics. The series is logically organized to fit the learning process. Each volume covers a given area of knowledge, which in itself is complete, but also prepares the student for the ensuing volumes.
I would have ranked this as number four or five on the topics a student needs to know about elctronics as it jumps right into signals, amplitude and frequncies without discussing the kind of components and circuits it involves.
