Troubleshooting Electronic Circuits: A Guide to Learning Analog Electronics

Hands-On Analog Troubleshooting That Builds Real Skills

Working with analog circuits can feel mysterious when a design refuses to behave. Ronald Quan’s Troubleshooting Electronic Circuits: A Guide to Learning Analog Electronics cuts through that confusion with a practical, step-by-step approach to building, debugging, and improving real circuits. Instead of lengthy theoretical digressions, the book focuses on the working techniques that help you get a circuit running—and keep it running.

What You’ll Work Through

• Setting up reliable solderless breadboards and power sources
• Choosing and testing basic electronic components
• Working with diodes, rectifiers, Zener diodes, and LEDs
• Understanding and troubleshooting bipolar junction transistors
• Debugging discrete transistor amplifiers
• Using analog integrated circuits, including amplifiers and voltage regulators
• Tackling audio circuits and ham radio circuits related to software-defined radio
• Exploring timer circuits built around the 555 chip and CMOS logic

From Breadboard to Manufacturable Circuit

Many hobbyist guides stop at “it works.” Quan goes further by analyzing poorly conceived circuits and showing how to improve them for repeatability and manufacturability. The lessons drawn from real-world failures help you look at a schematic with a more critical eye—so you can avoid common mistakes before they become time-consuming problems.

Who This Book Is For

This guide is ideal for electronics hobbyists, engineering students, and professionals who want to strengthen their analog troubleshooting skills. Whether you’re reviving an old project, building your first transistor amplifier, or debugging a custom audio circuit, the examples and explanations give you a solid foundation for confident work.

A Clear Path Through Analog Electronics

Quan brings over three decades of industry experience to the page, and it shows in the practical details. The book’s project-driven chapters keep the focus on what you can measure, test, and improve. By the end, you’ll have a set of reliable diagnostic habits that apply far beyond the specific circuits covered here.
