Analog television (or analogue tv) encodes television and transports the photograph and audio data as an analog signal, that is, by different the amplitude and/or frequencies of the broadcast signal. Analog tv, like all other motion picture systems, exploits the properties of the human eye to create the illusion of relocating pictures. Analog tv support is the standard Television method. Analog tv has been the standard broadcast engineering considering that the inception of television employing magnetic waves to transmit and screen pictures and audio. Analog tv has an facet ratio of 4 by 3, which implies the display screen is four models extensive by 3 models substantial.

HDTV
