How does radio waves carry information
Did you know?
WebA modulated radio wave, carrying an information signal, occupies a range of frequencies. The information ( modulation) in a radio signal is usually concentrated in narrow frequency bands called sidebands ( SB) just above and below the carrier frequency. WebMay 28, 2024 · When you press one of the buttons, the remote generates a systematic series of on/off infrared pulses that signal a binary code (a way of representing any kind of information using only zeros and ones, which computers use). So a short pulse of infrared could signal a 1 and no pulse could signal a 0.
