This 10th edition lab book, Experiments in Digital Fundamentals, ISBN 978-0-13-712965-2, can be used in place of the 11th edition. No need to spend extra money on the newest edition of this book. I have taught Digital Electronics several times and I allow my students to use previous editions of textbooks to save their hard-earned money! There is very little difference between the 10th and 11th editions. The 2 lab books in this eBay listing are brand new!
