    how I can find Δf?

    What use?
    Δf = 4%* fc

    or

    Δf = 4%* fm

    Hi,

    I guess you mean what is the delta frequency?

    If you have a 1000Hz signal that varies by plus and minus 10 percent, what is the total variation in frequency? Keep in mind that it goes below 1000Hz and above 1000Hz, not just one or the other.
