Signal Generation
Function: To create or produce the original content. Importance: It is the initial step that determines the quality and content of the broadcast.
Multiplexing
Function: To combine multiple signals into one for transmission. Importance: Enables efficient use of bandwidth and infrastructure.
Propagation
Function: The movement of the signal through the transmission medium. Importance: Influences the reach and the potential audiences of the broadcast.
Transmission Medium
Function: To act as the physical pathway for the signal. Importance: Medium determines transmission quality and possible distance.
Demodulation
Function: To retrieve the original information from the modulated carrier wave. Importance: Necessary for the audience to perceive the intended content.
Output
Function: To present the final content to the end-user. Importance: The final stage where the audience consumes the broadcast, assessing its quality.
Decoding
Function: To translate encoded signals back into a usable format. Importance: Allows the content to be displayed or played back on devices.
Antenna
Function: To radiate the signal into the transmission medium. Importance: Critical for the coverage area and reception quality of the broadcast.
Transmitter
Function: To amplify and send the signal to an antenna. Importance: Determines the range and strength of the broadcast signal.
Reception
Function: To capture the signal by the receiver's antenna. Importance: The quality of reception affects the user's experience and satisfaction.
Encoding
Function: To convert content into a digital or specific signal format. Importance: Essential for ensuring compatibility with transmission standards and devices.
Modulation
Function: To modify the signal to carry information over a medium. Importance: Allows effective transmission through different types of media like air or cable.
