## Course Description & Benefits

Learn Telecommunications by Simulation teaches you the fundamentals of Analog & Digital Telecommunications by actually building the various fundamental waveforms in Mathematics software. This allows you to study their time behavior using a Scope and their frequency behavior using a Spectrum Analyzer just as you would in real life. An inexpensive companion hardware tool the RTL-SDR also allows you to capture real world signals and compare them to your math models.

• Understand the difference between Baseband & Modulated signals
• Learn how wireless signals are created and transmitted
• Learn the various ways a carrier signal can be modulated: amplitude, frequency, phase & various combinations
• Understand the structure of modern Telecommunications systems such as AM, FM, Amateur Radio, Marine, Cellular, WiFi, Satellite,

## FAQ

• Is this course right for me?

You can get an excellent idea of the teaching and application of this method by looking at the CTEL YouTube Channel & Blog: https://www.youtube.com/user/clarktelecom https://jeremyclark.ca/wp/

• What background do I need

Studying the various modulation techniques is essentially different ways of modifying a sine wave. This is why an understanding of Trigonometry is important. Basic calculus like differentiation and integration become important in phase modulation, but is not essential.

• Do I need to buy hardware?

It is recommended that you purchase an RTL-SDR. They are very inexpensive (\$25) and incredibly useful. You don't have to have one, but it makes visualization very powerful. You can also use an HRF1 or Adalm-Pluto if you have one.
