    Analog and digital modulation facilitate frequency division multiplexing(FDM), where several low pass information signals are transferred simultaneously over the same shared physical medium, using separate Passband channels several different carrier frequencies.

    Whereas a Passband signal is also modulated so that it occupies higher frequencies(compared to a baseband signal which is bound to the lowest end of the spectrum, see linecoding), it is still occupying a single channel.

    The key difference is that what is typically considered a broadband signal in this sense is a signal that occupies multiple(non-masking, orthogonal) Passbands, thus allowing for much higher throughput over a single medium but with additional complexity in the transmitter/receiver circuitry.
