About this book
Circuit decoders and encoders are silent workhorses in nearly every digital system, translating between binary codes and physical actions. Yet most engineers and makers only know the parts they've used before, relying on datasheet pinouts without a solid grasp of the underlying architecture or the trade-offs between different logic families and configurations. This handbook changes that, offering a structured, practical journey through these fundamental building blocks.
Starting with the core concepts of binary encoding and decoding, the book then guides you through the landscape of available types, from simple 3-to-8 line decoders to complex priority encoders and bus-oriented circuits. You'll learn to read datasheets critically, match specifications like propagation delay and fan-out to your project's needs, and install these components correctly on a PCB or breadboard. With dedicated chapters on maintenance, troubleshooting, and the business opportunities in this niche, it is a complete resource for anyone who wants to move past guesswork and toward engineering competence.
Written in a clear, neutral tone, this is not a marketing brochure or a cut-and-paste of manufacturer specs. The author, an experienced editor-ghostwriter, has distilled decades of practical electronics experience into a reference you'll keep on your bench, not on a shelf.
Reader Reviews

★★★★★I bought this mostly for the maintenance and troubleshooting chapter, and it didn't let me down. The explanation of why a 7-segment display might show a phantom '8' due to floating inputs finally made it click for me. I'd have liked a bit more depth on high-speed LVDS encoders, but it's a solid, practical handbook that cleared up a lot of fuzzy areas for me in a weekend.
Charles King
★★★★★It's a decent reference, and the chapter on choosing the right part for the job genuinely helped me spec a replacement for a dead encoder on a machine. I found the tone a bit dry, and some parts felt like a recap of what I already knew from an intro digital logic class. The glossary is handy, but I thought the business opportunities chapter stretched to fill space. A useful book to have, but not the be-all-end-all.
Christopher Lewis
★★★★★This is exactly the kind of practical reference I've been hunting for. I'm a senior tech at a smaller automation firm, and we work with incremental encoders constantly. The chapter on installation alone saved me from a headache - the author's explanation of the difference between quadrature output and simple pulse outputs, and how to wire them, is the clearest I've ever seen. There's no fluff here, just solid, usable information.

★★★★★Huge fan of this project. I'm a hobbyist building my own CNC controller, and I was pretty lost between raw encoder datasheets and forum posts. This book ties everything together into one coherent story, from the basic logic gates to the practical specs like fan-out and propagation delay. It doesn't assume you're a beginner, but it also doesn't leave you hanging when a topic gets hard. Worth every penny for the troubleshooting chapter alone.
