FM Rainbow

FM Rainbow, or frequency modulation rainbow, refers to a method of transmitting FM radio signals across different frequency bands. It visualizes the spectrum of frequencies used in FM broadcasting, showing how various channels are allocated and spaced to avoid interference. The term "rainbow" highlights the range of frequencies and the colorful representation of these different channels. This technique enhances sound quality in radio broadcasts and allows for multiple stations to operate within the same frequency spectrum without overlap, ensuring clear reception for listeners.
