    Dear all

    I am looking for a circuit which will change its resistance according to the the input clock.
    One circuit I have in mind which I have attached here, it's just a thought. Sorry image is no clear.

    When diode on then Resultant will be different wit diode off.


    If any one knows some better option or some nice IC it will be very hlpfull.
