The Physics Behind Electronics

While traditional textbooks treat electronics as a set of techniques, the growing availability of affordable acquisition boards and user-friendly software has diminished the need for expertise in circuit design. Nonetheless, physicists still need to comprehend concepts like stability, impedance matching, noise, and the advantages and limitations of signal sampling. The book concludes by examining scenarios involving high frequencies where wires act as waveguides and addressing noise sources from thermal agitation and the corpuscular nature of current. Theoretical concepts are reinforced with solved exercises, and practical "in-the-lab" sections guide readers through experiments using affordable kits and instruments, requiring minimal electronic prototyping knowledge.
