A theoretical-practical journey to understand how information can be transmitted through radio waves. The story begins with telegraphy and continues through digital modulations and beyond.

Required materials (all provided by the instructor):

• Various types of transceivers
• Spectrum analyzer
• Laptop for demonstrations

Workshop content

• Theory of signal propagation
• Brief history of telecommunications
• Why “modulation” is necessary
• Telegraphy
• Amplitude modulation (AM) and its efficiency challenges
• Frequency modulation (FM)
• Digital modulations (FSK, PSK, QAM)
• Practical radiofrequency exercises

Duration: 2 hours
