Real Analog - Circuits 1
"Real Analog" is a comprehensive collection of free educational materials that seamlessly blend hands-on
design projects with
theoretical concepts and circuit analysis techniques. Developed for university "Circuits" classes by
practicing engineers
and experienced educators, Real Analog is centered on a newly-written 12-chapter textbook and features:
- More than 40 video lectures that follow the text, each with downloadable lecture notes
- Exercises designed to reinforce textbook and lecture topics
- Homework assignments for every chapter
- Multiple design projects that reinforce and extend theoretical concepts
- Worksheets and videos to help students complete design projects outside of the lab.
Design projects use Digilent's
Analog
Discovery
and
Analog
Parts Kit
that together include everything needed to
build and test a wide variety of analog circuits - the Analog Discovery includes a dual-channel
oscilloscope, waveform
generator, power supplies, digital I/O channels and more, and the Analog Parts Kit includes a breadboard,
jumper wires,
more than 20 integrated circuits from Analog Devices, and a wide variety of sensors, resistors, capacitors,
discrete
semiconductors, and other components.
Real Analog, the Analog Discovery and Analog Parts Kit form the core of a world-class engineering
educational program that
can be used by themselves or in support of existing curricular materials. Students with their own design
kits learn more,
learn faster, retain information longer, and have a more enjoyable experience - now every student can take
charge of their
education for less than the cost of a textbook!

Chapter 1: Circuit Analysis Fundamentals
|

|
|
|
|
|
|
Chapter 1 text |
|
In this chapter, we introduce all fundamental concepts associated with circuit analysis.
Electrical circuits
are constructed in order to direct the flow of electrons to perform a specific task. In
other words, in
circuit analysis and design, we are concerned with transferring electrical energy in order
to accomplish
a desired objective.

Chapter 7 text |

First order systems are, by definition, systems whose input-output relationship is a first
order differential equation.
A first order differential equation contains a first order derivative but no derivative
higher than first order - the
order of a differential equation is the order of the highest order derivative present in the
equation.

In this chapter, we will provide a very brief introduction to the topic of state variable
modeling. The brief
presentation provided here is intended simply to introduce the reader to the basic concepts
of state variable
models, since they are a natural - and relatively painless - extension of the analysis
approach we have used in
Chapters 7 and 8.

Chapter 12: Steady-State Sinusoidal Power

|
|
|
Chapter 12 text |
|
In this chapter we will address the issue of power transmission via sinusoidal (or AC)
signals. This topic is
extremely important, since the vast majority of power transmission in the world is performed
using AC voltages
and currents.
