In my previous blog post, Becoming a Licensed Engineer Part 3 of N, I listed half of the websites that were invaluable to me during my preparations of the Electrical P.E. Exam. The following is the rest of the links that I used throughout my studies:

**Control Systems links:**

*Block Diagram Algebra Brute Force*

*Block Diagram Algebra*

*DEQ Transfer Functions*

*Control Systems Engineering – UWE Lecture 2 (I found the information between minutes 12 to 39 most useful)*

*Control Systems Engineering – UWE Lecture 3*

*Control Systems Engineering – UWE Lecture 4 (I found the first 11 minutes most useful)*

*Control Systems Engineering – UWE Lecture 5 (I found the first 35 minutes most useful)*

*Control Systems Engineering – UWE Lecture 7*

**Communications Links:**

*Sampling Theorem: Introduction*

The following is a link to numerous great Fourier Series videos:

*Best Damn Tutoring – Fourier*

The following is a link to MIT Communications Lectures:

*MIT Communications*

*Shannon-Hartley theorem*

*What You Really Need to Know About Sample Rate*

**Electromagnetic Fields Links:**

*Wikipedia – Dot Convention for Transformers*

*Electronics Tutorials (I found slides 1 through 4 most useful)*

*Inductive Reactance*

This is a great Antenna Theory Website, I searched through most if not all of this website:

*Antenna-Theory.com*

**Miscellaneous helpful links that I’m not sure how to categorize into the various EE subjects:**

There wasn’t much math on the test but I did refer to this link during the test:

*Trigonometric Functions*

*Inverse Tangent and Cotangent*

*Two-port network*

*Crystal Oscillator Circuits*

As you can tell from the title, this is the last blog post for this series. I hope we have provided some useful information to help you throughout your studies. If you end up using any of the information provide, we welcome feedback. We’d love to improve this blog post so it can be more useful to others. Good luck!
