    Hi, I would like to generate a signal source without period and which
    covers wide frequency band. It is like a noise-like wave form but I
    can control the frequency band. I can not make it by sin source, piece
    wise linear source, dc source. Can anyone give me some idea?
    Appreciate it.

    What kind of analysis are you expecting to simulate in? You could use some
    kind of impulse, followed by a filter to band-limit it (using a svcvs, for
    example, which is a laplace voltage controlled voltage source). But that's
    pretty nasty...
