So, what are you gonna do, Barry? About work? I don't know. I want to do my part for the hive, but I can't do it the way they want. I know how you feel. - You do? - Sure. WebHow do radio waves carry information? The basic principle is simple. At one end, a transmitter “encodes” or modulates messages by varying the amplitude or frequency of the wave – a bit like Morse code. At the other, a receiver tuned to the same wavelength picks up the signal and ‘decodes’ it back to the desired form: sounds, images, data, etc.
