Final answer:
In connecting a TV to a tuner card, the traditional video and audio signals use AM and FM transmissions, respectively, while modern TV, including cable and satellite, often operates at higher frequencies, especially for HD content. Coaxial cables with F-type connectors are used for their ability to effectively carry these signals with minimal interference.
Step-by-step explanation:
When connecting a TV input to a tuner card using a coaxial cable and F-type connectors, it's essential to understand the underlying technology of TV signals. The traditional TV video signal is transmitted using Amplitude Modulation (AM), while the audio signal utilizes Frequency Modulation (FM).
These transmission methods are analogous to how an old-fashioned roof antenna sends and receives signals. On the other hand, more modern methods such as satellite dishes and cable TV use much higher frequencies to transmit content, which now often includes high-definition (HD) formats.
Coaxial cables, which are used extensively in audiovisual connections, have a center core and an external conductor divided by insulation. This structure is highly effective at carrying signals to homes, offering better protection against signal interference compared to other types of cables, which is why it's used in cable TV and other data transmission systems.
Cable TV networks distribute their programming through coaxial or fiber optic cables, and since they do not use airwaves for broadcast, cable networks can provide specialized programming nationally even without local affiliates. They do so by acquiring broadcasting rights for the cable stations that complement their viewers' interests.
