The Fast Track to Determining Transfer Functions of Linear Circuits is now available for orders. Thank you to Ken Coffman from Faraday Press who has worked with the materials I provided to assemble a 267-page book. The book can be seen as a crash course on fast analytical circuits techniques or FACTs and includes 7 chapters. Providing solid theoretical foundations and a refreshing look at transfer functions, the book will help students willing to speed-up ac analyses of linear circuits but also seasoned engineers facing circuits they would like to study without diving back into their university books. Unlike other books on the subject, I purposely slowed down the pace and took baby steps via numerous illustrations to show how to quickly and painlessly determine transfer functions.

The four first chapters teach what a transfer function is and how to assemble it the right way, in a compact and readable format. Chapter 5, 6 and 7 respectively cover 1st-, 2nd- and 3rd-order transfer functions in comprehensively-documented examples, softly starting from the simplest ones to more complicated structures. The table of content is here. Chapters are organized as follows:

Chapter 1: this chapter starts smoothly by introducing poles and zeroes and how they link with time constants. In this chapter, the 6 possible transfer functions are introduced with the concept of low-entropy expressions which consists of writing expressions in the most compact and insightful way.

Chapter 2: learn how to turn the stimulus off and identify a pole or a zero in a few seconds, without writing a single line of algebra! Owing to the beauty of the methods, in many cases, you will be able to write the transfer function by inspecting the network, without resorting to equations.

Chapter 3: zeroes take place in the numerator of a transfer function. Learn how you can find where they hide in a circuit just by identifying transformed shunts or open-circuits. SPICE will help you check your results and it is an invaluable tool to accompany you during the acquisition of the skill.

Chapter 4: in this chapter, you will discover how it is possible to reuse the denominator time constants for finding the zeroes in the numerator. The generalized transfer function is very useful in complicated circuit where a null double injection is difficult to run or not obvious at first glance.

Chapter 5: this chapter is entirely dedicated to 1st-order transfer functions with all steps detailed to determine input or output impedances, gains etc. 29 examples are fuly documented.

Chapter 6: we are now entering the worlds of 2nd-order networks, featuring two energy-storing elements. Many examples detail how to handle these circuits, mostly analyzed with simple sketches. 25 examples are illustrated.

Chapter 7: in this last chapter, I have documented 10 examples of 3rd-order networks using FACTs. You'll be amazed how writing the transfer function of 3 cascaded RC networks only takes a few minutes!

As with the previous books, I will collect comments and findings from readers to gather them in the errata file.
