    Bandwidth and signal speed

    I heard someone said signal speed is limited due to bandwidth.

    What has bandwidth to do with signal speed?

    Re: Bandwidth and signal speed

    I believe that they are uncorrelated, the velocity of propagation is given in terms of permeability and permittivity and is not a function of bandwidth. However, if you are talking about things like transfer rates then Shannon's capacity theorem states that maximum rate of guaranteed transfer is given as

    Capacity = Bandwidth*log_2(1+SignaltoNoiseRatio)
