Activity 1.3.3
Introduction
Just a few short weeks ago, most of you knew little or nothing about digital electronics. Now you are about to build and simulate a complete design. This design, the Board Game Counter, will be your first exposure to combinational and sequential logic, which are the basic building blocks of digital electronics and the topics of study for the majority of this course.
In this activity you will use the Circuit Design Software to build and test the complete digital logic section of the Board Game Counter design.
conclusion
1. The combinational logic in Board Game Counter was AOI logic. What are three gates that are used to implement AOI logic?
2. On the 74LS74 D flip-flop, the CLK input has a small triangle. The PR (preset) and CLR (clear) inputs have a circle. What do these symbols mean?
3. What is the primary characteristic that differentiates combinational and sequential logic?

conclusion
1. The combinational logic in Board Game Counter was AOI logic. What are three gates that are used to implement AOI logic?
- OR, AND, & NOT
2. On the 74LS74 D flip-flop, the CLK input has a small triangle. The PR (preset) and CLR (clear) inputs have a circle. What do these symbols mean?
3. What is the primary characteristic that differentiates combinational and sequential logic?
- sequential depends on previous inputs combinational does not.
