What is the primary function of a transmitter in TBS communications?

The primary function of a transmitter in TBS communications is to convert information into radio signals for transmission. This process involves taking the data that needs to be sent, such as voice, video, or other forms of information, and modulating it onto a carrier wave. This modulation allows the data to be effectively transmitted over the air or through other mediums to be received by the intended receiver. By transforming the information into a format suitable for radio propagation, the transmitter plays a crucial role in communication systems, ensuring that data can be sent and received accurately over distances.

Other options, while related to the transmission process, do not define the primary role of a transmitter. For instance, capturing radio signals refers to the function of a receiver, while filtering noise pertains to improving signal quality rather than the initial transmission role of the transmitter. Enhancing signal strength can occur in various stages of a communication system but does not solely define the transmitter's primary purpose.
