    Greetings skumart.31dec,

    I have moved your question from its position inside one of the other existing threads into its very own thread.

    In the future, please start your own thread whenever you want to ask a question. Tacking your question onto another thread is not a productive way to obtain assistance for your unique set of circumstances.

    The steepness of the cutoff is determined by the number of poles or orders the fiter is made with.
    The sharpness of the cutoff corner is determined by whether the filter is a Bessel or a Butterworth type of filter.

    Do you happen to have a particular filter circuit for which you would like to derive the transfer function?
