    Study Notes

    Introduction to Electronic Communication Systems

    • Learning objectives include explaining the functions of electronic communication system components, discussing modulation and multiplexing, and defining the electromagnetic spectrum and its segments.

    Significance of Human Communication

    • Communication is the exchange of information, conveying thoughts, ideas, and feelings.
    • Involves verbal, nonverbal, print, and electronic processes.
    • Major barriers include language differences and distance; early humans communicated face-to-face.

    Communication Systems Overview

    • All systems consist of three main components: transmitter, communication channel/medium, and receiver.
    • The message, referred to as information or intelligence signal, is transmitted as an electronic signal.

    Components of Communication Systems

    • Transmitter: Converts electrical signals to suitable transmission formats; includes oscillators, amplifiers, tuned circuits, modulators, and synthesizers.
    • Communication Channel: Medium for signal transmission; includes wire conductors, fiber-optic cables, and free space (radio).
    • Receiver: Accepts transmitted messages, converting them back to understandable forms; includes amplifiers, oscillators, filters, and demodulators.

    Two-Way Communication

    • Most electronic communication allows for two-way interaction, requiring both transmitters and receivers in systems known as transceivers.
    • Transceivers integrate all circuits in a single housing, often sharing power supply circuits.

    Types of Electronic Communication Systems

    • Electronic communications can be classified based on their specific characteristics and applications.
