TVsignalen

TVsignalen, also known as television signals, are the electromagnetic waves that carry television programs from a broadcaster to a viewer's television set. These signals are a form of radio waves and are transmitted over the air or through cables. Historically, television broadcasting was done using analog signals. Analog signals represent sound and image information as continuous waves. When these waves are received by a TV antenna, they are demodulated to reconstruct the original audio and video.

In recent decades, the world has largely transitioned to digital television signals. Digital signals represent information as discrete binary data (ones and zeros). This transition offers several advantages, including improved picture and sound quality, more efficient use of broadcast spectrum, and the ability to carry additional data services like electronic program guides. Digital signals are more robust against interference, meaning viewers are less likely to experience static or "snow" on their screens.

The reception of TVsignalen can occur through various methods. Terrestrial television broadcasting involves transmitting signals from ground-based towers to antennas on homes. Cable television delivers signals through coaxial or fiber optic cables. Satellite television receives signals from satellites orbiting the Earth, which are then relayed to a satellite dish at the viewer's location. Each method of reception requires specific equipment, such as an antenna, a cable modem, or a satellite receiver. The type of TVsignalen received determines the compatibility of the reception equipment and the television set itself.
