    When you could fit “more than one” “refular” signal in the given spectrum, it's called wideband. To a Morse-code operator, 500Hz would be wideband, because you can almost effortlessly fit 10 or more signals in that bandwidth. An AM radio signal that is 20kHz wide, allows for audio of up to 10kHz wide to be transmitted, double the going rate.
