    frequency domain in system analysis

    can any one till me why to use frequency domain in system analysis and not the time domain?

    It depends on the problem.

    ok
    but in control engineering we r always using frequency domain in block reduction and concatenation

    they say that it is more easy since it transforms differential and integral equations into algebric equation and because it makes block concatenation extremely easy

    but are those the only reasons??????

    i hate getting used to something without understanding it very well

    My experience is that Laplace domain is more common, but then that is only
    another way of writing the integro-differential operator that the block
    represenrs, and also by a simple change of variable converts to the
    frequency domain.

    But all this assumes that we have linear operators.
