Build digital electronics from the ground up-and take it all the way to practical circuits you can use.

This book guides you through the core principles of digital technology with a strongly hands-on approach. You’ll begin with the essentials: signals, devices for working with them, and what “logic 0” and “logic 1” mean in real hardware. Simple demonstration setups made from easy-to-find parts (LEDs, diodes, resistors, switches) help you see how logic behaves, making the theory click before you move on.

From there, you’ll explore a wide range of logic elements and how they’re implemented, including classic logic families such as TTL and CMOS. The fundamentals section covers the building blocks of digital systems: flip-flops, Schmitt triggers, registers, counters and dividers, encoders/ decoders, multiplexers/demultiplexers, plus A/D and D/A conversion and timing circuits.

Next, the book invites you into “new ideas” in digital electronics-universal logic elements, unconventional approaches (including thyristor-based and fractional logic), and creative logic functions that can inspire original designs.

Finally, a large, well-organized collection of application circuits turns knowledge into projects: electronic switches and selectors, pulse generators, PWM regulators, frequency multipliers/dividers, phase shifters, and digital filters.

Study it deeply, and you’ll gain not only understanding-but the ability to design and debug digital circuits independently.
