Before Taub and Schilling, most textbooks took a black-box approach to digital logic. They taught that "a logic gate is a gate." Taub and Schilling, however, started with the transistor. They famously used the for MOSFETs and BJTs, explaining how voltage levels control current flow before introducing Boolean algebra.
Detailed breakdowns of R-2R ladder networks, successive approximation registers (SAR), and dual-slope integrating analog-to-digital converters. Comparative Analysis of Logic Families Before Taub and Schilling, most textbooks took a
