WebFigure 13.5.2 Electromagnetic waves are used to carry communications signals by varying the wave’s amplitude (AM), its frequency (FM), or its phase. Cell phone conversations, and television voice and video images are commonly transmitted as digital data, by converting the signal into a sequence of binary ones and zeros. WebSo ground wave transmission is limited to a frequency of 1500 kHz. Q.70 Why sky waves are not used in the transmission of TV signals? Sol. TV signals have frequency much higher than 30 MHz. Such high frequency signals cannot be reflected by the ionosphere. Therefore, sky waves are not used in the transmission of TV signals. happy gilmore yelling at ball gif
