General Course Information

This course, as its name suggests, is about resonances - where do they cause problems, where do they solve them and how can they be measured at all?

These questions and more are dealt with and clarified in the topics Laboratory Basics, Resonance Circuits, Active Filters and Passive Filters.


Course Content

In this MOOC we cover the basic properties of resonance circuits, active filters and passive filters. We will also explain the basic function and application of some important measuring devices. The aim is to provide both the mathematical tools and the practical understanding to be able to build, calculate and measure appropriate circuits independently. For this purpose, theory, calculation, simulation and practical examples are available.

The course is divided into four parts:

  1. Lab Basics
    • Multimeter
    • Function Generator
    • Power Supply
    • Oscilloscope
  2. Passive Filters
  3. Active Filters
  4. Resonance Circuits

Course Goals

The learning objectives of the individual sections are divided into four learning objective taxonomy levels and are detailed again in the respective sections. For the sake of simplicity, only the learning objectives of the highest taxonomy level are listed here.

Lab Basics
  • Select the appropriate (best possible) probe for a measurement with an oscilloscope for a given problem.
  • Identify and solve problems in the measurement setup.
  • Develop a suitable measuring circuit to determine a known resistance using a multimeter based on given parameters.
Passive Filters
  • Design a 2nd order high pass filter for a given cutoff frequency.
  • Select a T, L, or PI filter for a given load and input impedance.
Active Filters
  • Size a sallen-key/multiple-feedback filter with given characteristics and table of coefficients.
Resonance Circuits
  • Derive the formula for the resonance frequency of a simple RLC combination.

Previous Knowledge

The MOOC assumes only some basic knowledge of electrical engineering. This includes:

  • Ohm's law,
  • Kirchhoff's circuit rules,
  • Alternating and direct current,
  • Basics of electrical components (resistor, coil, capacitor, voltage and current sources).
  • Basics of electronics (diodes, bipolar transistors, MOSFETs, transistor circuits and operational amplifiers, see ElectrONiX - Amplifiers).

Course Procedure

Each unit is structured as follows:

  1. The first videos lay the theoretical foundations of each unit.
  2. These Videos are followed by a voluntary self-examination to check the theoretical knowledge.
  3. The following block deals with practical examples,
  4. again followed by a voluntary self-examination.
  5. For the particularly motivated, we offer additional material. This can be simulation examples or detailed elaborations.
  6. Finally, there is a test. In order to obtain a certificate, at least 75% of the points must be achieved.
  7. Positive completion of the test results in receiving a badge.

Questions can be asked in the accompanying forum. These can then be answered by both the course creators and the participants.


For actively participating in the course you will receive an automatic certificate which includes your username, the course name as well as the completed lessons. We want to point out that this certificate merely confirms that the user answered at least 75% of the self-assessment questions correctly.

In addition, a badge is created for each unit, which can be downloaded as an image.
