7 Notes Legend The notes for this course are organized into specific sections. You are responsible on assignments and exams for sections with a blue background title and star, as below: The following is a list of section types that you will encounter: Pre-Reading You should read these sections before the lecture whenever possible; they will make the lecture much easier to understand and more useful to you. It will be assumed that you have read these before coming to class. Lecture Notes These include copies of any circuit diagrams and other graphs to save you time (and provide tidy notes). Space to complete all examples is included; simply copy from the board into your notes. In-Class Break Bored in class? Can‟t stay awake during that Friday afternoon (or Tuesday evening) lecture? Read one of these for a quick change of pace, and maybe an interesting fact or bit of practical knowledge you can use later! Real-World Example A detailed example from the real-world relevant to the material just covered. This course has the potential to be one of the most practical courses you take; hopefully these will give you some interesting ideas about how to apply the course content. Project These sections outline detailed, real-world projects which you can build and use at home. Practice Problems A number of practice problems will be included at the end of every chapter. Problems for which solutions are provided are clearly marked. Tip Small but relevant bits of information about the course or related topics.

8 Chapter 1 Frequency Domain Analysis
9 What is the Laplace Transform? As you may have seen in previous courses, such as ECE110 or control systems courses, the Laplace Transform is a type of integral transform a linear operator which is most useful in electronics for converting a time-domain signal, , , to a complex or frequency- domain signal, . The formal mathematical definition of the Laplace Transform is given for a function, , where , as the following: { } ∫ While the Laplace Transform of any time-domain function can theoretically be calculated directly using the above formula, we will see that it is much simpler in most cases to instead use tables and properties of the transform. Why do I need to learn this? The main use of the Laplace Transform is to allow us to work in the frequency domain for circuit analysis. This is beneficial for a number of reasons. First, the basic math behind determinin g a circuit‟s response to an arbitrary signal may be significantly less complex when using the frequency domain. This is seen in the graphic from the start of the chapter: Pre-Reading: Introduction to Laplace

10 In the time domain, we have some signal, , for which we can to determine the output of a circuit, . For the time-domain system, the effect of the system is represented by the function, . To determine the output of the system, one must apply convolution in the time domain:

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
