COMMUNICATION SYSTEMS

This topic explores the basic principles of communication systems, including analogue, digital, optical, and wireless methods. Learners build simple systems, analyse stages of communication (encoding, transmission, decoding), and investigate signal propagation techniques and factors affecting it like distance and interference. They also research real-life applications in weather monitoring, telemedicine, and telecommunications. Aligned with the Zambia CBC's emphasis on technology and real-world relevance, this topic prepares learners to understand modern information transfer. Knowledge of communication systems is valuable for ECZ exam preparation, particularly for questions linking Physics principles to contemporary technological applications.
