This document contains important questions from chapters 5, 7, 8, and 9 of a Digital Logic Design course. In chapter 5, it asks students to draw logic diagrams, truth tables, and output waveforms for 4-bit ripple up and down counters as well as a 4-bit synchronous up/down counter. Chapter 7 asks students to define and explain different types of shift registers and draw a diagram for a 4-bit bidirectional shift register. Chapter 8 asks students to explain the characteristics, operation, and basic components of digital ICs including RTL, DTL, and TTL gates. Finally, chapter 9 asks students to realize logic functions using PLA and PAL diagrams.
