    Wiener filter for equlization

    man, i found that equalisation is improved if you do it in time domain. try to derive your filter formula in time domain and tell me what happen.

    Problem with results of convolved functions

    Convolution... i think i will be distorted. from x(t) * h(t) ====> X(f).H(f) using FFT, this call fast convolution, with is the same result. then H(f) will be sin(x)/x function, which will distort spectrum of X(f) for sure... Yo!

    Virtual Ground and AC Ground ???

    when u are in AC analysis, u see anything in ACvoltage. AC ground is just something that is not AC... e.g. DC is AC ground. virtual ground is your own reference point for your analysis. u just assume it that this node is ground. at least in a circuit, u need a ground for reference. Yo!
