Design circuits containing integrated circuit components.
DefinitionDesign should include a
- problem statement specifying the desired circuit function
- schematic design and simulation
- verification of operation - breadboarding the circuit, testing, verifying, and describing demonstrated operation.
- What operational characteristics should the circuit have?
- How can a schematic or a computer-based simulation represent a circuit’s operation?
- How can a circuit be temporarily constructed for real-world validation of design work?

The student will plan and conduct investigations using experimental design and product design processes. Key concepts include
- the components of a system are defined;
- instruments are selected and used to extend observations and measurements;
- information is recorded and presented in an organized format;
- the limitations of the experimental apparatus and design are recognized;
- the limitations of measured quantities are recognized through the appropriate use of significant figures or error ranges;
- models and simulations are used to visualize and explain phenomena, to make predictions from hypotheses, and to interpret data; and
- appropriate technology including computers, graphing calculators, and probeware is used for gathering and analyzing data and communicating results.
