Radio and television are using electromagnetic waves to carry

Radio and television are using electromagnetic waves to carry. In radio, the people have the sound signals into electrical signals, and the signals from the high frequency oscillation wave propagation with the air circuit breaker space. In another location, people use the receiver receives these electromagnetic waves, which in turn signals back into sound signal, which is the general process of radio. In the TV, in power transformers as the radio signal as in sound processing, but also the image of the light signals into electrical signals, and these are joined together by two signals with high frequency oscillation wave propagation to the surrounding space, the television receiver Voltage stabilizer signals will be one of the electromagnetic wave and then back into sound signals and optical signals to display a screen of a television and voice from the loudspeaker.
