Activity 1.3.1
Introduction
Combinational and sequential logic are the fundamental building blocks of digital electronics. Combinational logic, which is sometimes referred to as "combinatorial logic”, is characterized by its output being a function of the current input value.
A variety of different logic gates can be used to implement combinational logic circuits. Many of these gates will be studied in future units of this course. In this introductory unit, we will limit our designs to AND, OR, and Inverter gates for the sake of simplicity.
In this activity you will use the Circuit Design Software to build and test your first combinational logic circuits.
Conclusion
1. From your life experiences, list 3-5 examples of products that you have used that contain combinational logic.
A search engine, A fire extinguisher(The fire extinguisher will not discharge until the pin has been pulled AND the lever has been squeezed), & the backup buzzer on a school bus.
2. Throughout this activity we used switches for the circuit inputs and a probe for the circuit outputs. Though this works fine for testing purposes, it is not practical for real-world applications of combinational logic circuits. List three input and three output devices that would be used with real world applications of combinational logic.
Input:switch, button, or pull lever
Output:Buzzer, light bulb, or probe
