Which of the following can be combined to form a composite signal for transmission?

The correct answer, which encompasses data packets, voice signals, and video signals, highlights the capability of these various signal types to be integrated into a single composite signal for transmission purposes.

In telecommunications, composite signals are often used to optimize bandwidth and improve the efficiency of transmission. By combining different types of signals—namely data packets, voice, and video—into a single format, it allows for the maximization of available resources. This is particularly significant in modern communication systems such as Voice over IP (VoIP) and video conferencing, where all three types of signals can be transmitted simultaneously over the same network infrastructure.

Data packets carry digital information which can include voice and video, enabling them to coexist on the same medium. Voice signals, typically in analog form, can be digitized and merged into data packets. Video signals, when digitized, can also be broken into data packets. This integration ensures the seamless transmission of multimedia content, facilitating effective communication and interaction.

Overall, the combination of these signals into a single composite allows for efficient use of network capacity, supports various applications, and enhances the user experience by delivering multiple types of information through a singular transmission channel.
