Fernsehsignal

Fernsehsignal refers to the electromagnetic wave that carries television programming from a transmitter to a receiver. Historically, these signals were analog, meaning they represented information as continuous waves. The broadcast spectrum used for television was divided into channels, each assigned a specific frequency range. Analog signals encoded both the video image and the audio information within this frequency band. The process involved modulating these components onto a carrier wave for transmission. Receiving the signal required an antenna to capture the electromagnetic waves and a television set to demodulate and display the information.

With the advent of digital television, the nature of the fernsehsignal changed significantly. Digital signals represent information as discrete binary data (0s and 1s). This allows for more efficient use of bandwidth and offers improvements in picture and sound quality, such as high definition and surround sound. Digital fernsehsignale are typically transmitted using terrestrial, satellite, or cable methods. The transition from analog to digital has been a global trend, enhancing the capabilities and reliability of television broadcasting.
