Putting It All Together: Analysis and Modeling Across Domains

In This Chapter

Looking at the big picture of signals and systems domains

Working with LCCDEs across both continuous- and discrete-time domains

Tackling signals and systems problems beyond the one-liner solution

Working across domains is a fact of life as a computer and electronic engineer. Solving real computer and electrical engineering tasks requires you to assimilate the vast array of signals and systems concepts and techniques and apply them in a smart and efficient way. For many people, putting everything together and coming up with real solutions is tough. My goal in this chapter is to help you see how various concepts interact and function in actual situations.

When you receive design requirements for a new project, the system architecture will likely contain a variety of subsystems that cover both continuous- and discrete-time. A powerful subsystem building block is the linear constant coefficient (LCC) differential equation and the LCC difference equation. These subsystems are responsible for implementing what are commonly referred to as filters.

Filters allow some signals to pass and they block ...
