Frequency components in a singnal.

From a book:
"The waveform is distorted because of different amounts of attenuation and phase shift suffered by different frequency components of the signal" Question: If there are different frequency components in a single, how do the ratio channels operate on a single frequency. A channel, for example, operates on the frequency 101. How can this happen when the signal contains components of differing frequencies? Thanks.

Any signal can be broken down into an infinite number of simple sinusoid components. Fourier is mind blowing.

The bandwidth of each US FM broadcast radio station is 200kHz, in the band from 87.8 MHz to 108.0 MHz. http://en.wikipedia.org/wiki/FM_broadcasting .

Frequency components in a singnal.
So, when we say ration station 106 (for example), we're talking about the Bandwidth. And Bandwidth means that this station/channel can be captured on all the frequencies in this band, right?

Another related question: When we say that a certain broadband/DSL connection has a bandwidth of say, 1 Mbps, what does that mean?
Thanks.

Thanks a lot! It was really helpful! Taking first course in Analogue Communication. :)
