Author: Ronald J. Tocci

Ronald J. Tocci is an engineering-technology educator associated with Monroe Community College and a longtime author of electronics textbooks. Digital Systems introduces the foundations of digital electronics, then advances through logic circuits, arithmetic, counters, registers, memory, programmable devices, and hardware description methods. Pearson’s current edition credits Tocci alongside Neal S. Widmer and Gregory L. Moss, reflecting the book’s development across successive revisions. Earlier editions circulated widely under the fuller title Digital Systems: Principles and Applications and were designed for learners in technical, engineering, computer-science, and related programs. The text’s progression from basic number systems to system projects has made it a durable teaching reference rather than a work tied to one hardware generation.
