Use digital technologies to communicate in a work environment

Modulation in Electronics and Telecommunications

• Modulation is the process of varying properties of a carrier signal with a separate modulation signal containing information to be transmitted.
• The modulation signal can be an audio signal, video signal, or digital signal.
• The carrier wave has a higher frequency than the message signal to enable transmission.
• Modulated carriers are transmitted as radio waves to a radio receiver in radio communication.
• Modulation is used for transmitting multiple channels of information through a single communication medium using frequency-division multiplexing (FDM).
• Cable television uses FDM to transmit many channels of information.
• BLUF (Bottom Line Up Front) is the practice of beginning a message with its key information.
• BLUF is used to provide the most important information first in a concise and powerful way.
• It is a standard in U.S. military communication to make messages precise and effective.
• BLUF can be used in writing, conversations, and interviews.
• Its purpose is to help manage a reader's load and ensure efficient communication.
• It differs from traditional styles where conclusions and recommendations are included at the end of a message.
