    Hi,

    I have searched the forum list, and found a 3 khz tone detector, but
    I could'nt make it work,

    is there any other simple way to make a tone detector but not with the lm567.

    Please some one comment on this, thank you very much in advance

    Hello,

    Why don't you want to use the ne567?
    There are lot of good examples with this IC.
    Take a look at this page of the EDUCYPEDIA.

    An other way is make a sharp filter and detect the signal that is seen after the filter.

    Greetings,
