This course is meant to create a pathway into learning about analog electronics, for people who are scared of the math and general trickery that usually comes with it. A hands-on approach is taken in this course through a combination of lecture and experimentation to teach you about the different basic ideas (AC vs. DC, filters and amplifiers) used in analog electronics.
- The Introduction
If you have never studied analog electronics before and want to get started learning about AC, DC, filters and amplifiers this is where you should start. This first lesson explains what this course is about, what tools you’ll need to follow along with the course and what expectations you should have from taking this course.
- AC vs DC Electricity
Understanding the difference between DC and AC electricity is the first step towards understanding analog electronics. In this less we will go over some theory about what AC electricity is, what it looks like and how it is different from DC electricity. Additionally, we will build an example AC circuit that generates a tone.
- Rectifier Diodes
In electronics, diodes serve a unique purpose in that they only allow current to flow through them in one direction, which makes them useful for blocking unwanted voltages and guiding current flow. In this lesson, we are going to use that unique property of diodes to rectify a simple AC signal into a flat DC signal.
- Zener Diodes
The zener diode is a special type of diode that allows current to flow through it in either direction, however only at certain voltages. In this lesson we will learn how zener diodes affect AC and DC signals and perform some experiments to see those effects.
- Passive Filters
The most basic passive analog filter comes by combining together a resistor and a capacitor or a resistor and an inductor. In this lesson we are going to learn how to build and design some basic RC and RL filters and see the effect of these filters on a simple audio signal.
- Lesson 6: RLC Filters
When we combine together a low pass RL and a high pass RC filter, the result is an RLC filter which filters both low and high frequencies out of a signal. In this lesson, we will learn how to build an RLC filter, see what formulas are necessary for designing an RLC filter and experiment with understanding the effect an RLC filter has on an audio signal.
- Active Filters
This type of analog filter is one that utilizes op-amps which can make sure the input signal is the same strength as the output signal. In this lesson we will build an active band-pass filter and see the effect it has on an audio signal when we vary its parameters.
- OpAmp Amplifier
When it comes to analog electronics, amplifiers are just as important as filters since they serve the purpose of amplifying filtered signals. In this lesson we will build a simple single transistor amplifier and see its effect on an AC sine wave input.
- OpAmp Amplifier
A different type of standard amplifier uses what is called an op-amp. This type of amplifier is very easy to setup and design with widely available formulas for how they work. In this lesson we will put these equations to work and build a basic 741 opamp amplifier, testing it out with an audio input signal.
- Design An Audio Amplifier
Designing a general purpose audio amplifier is a time tested favorite project of many electronics students. It shows that you are comfortable with building circuits and that you can actually make something useful! In this lesson, we will go through the process of designing a simple audio amplifier to make a very quiet audio signal really, really loud.
Generally, electronics is a difficult subject mathematically, however theoretically it's actually not as bad if you take a hands-on approach and create vivid imagery to demonstrate what is going on. Using this approach, virtually anyone with a basic math background and a desire to know more about electronics can get started. So the following prerequisites are necessary for this course:
This Introduction To Analog Electronics course will be split up into 10 lessons with the lecture video for each lesson hosted on youtube. The lectures will be 8-13 minutes in length so that you have enough time to see the information and can go over it twice to perform any of the experiments while following along with the video. Each lecture will contain 4 main sections: an introduction, a plain english explanation, theory and real world example. In addition, each lesson video will be hosted at PyroEDU with downloadable offline information and material like homework, schematics, formulas and parts information.

This course is meant to take you, the learner, from a blank slate to a more informed individual by teaching about analog electronics in a hands-on way, as the lecture videos will emphasize and guide you with experimentation. You should expect to learn the basic concepts used in the analog domain like AC vs. DC electricity, passive filters, active filters and different types of amplifiers. Beyond that, you should also expect to get a better 'feeling' for what it takes to make an all-analog-hardware design.

From there you can access all of the lectures (as we do them) and download homework, schematics, formulas and extra parts information.
Hello! Aside from building many electronics tutorials and projects, and posting their full hardware schematics and source code on PyroElectro.com, I studied computer and electrical engineering at university and have Bachelor's + Master's degrees in the subject. My work is typically more slanted to digital hardware, however the basics are the same no matter if you're an analog designer or a digital designer.
