Fourier transform of the delta function

Hello,

Any suggestions for the evaluation of the following ?
FourierTransform[
    KroneckerDelta[f-(-1 + 10^(n T/c)/b)], f, t]

or even this :
FourierTransform[
    DiracDelta[f-(-1 + 10^(n T/c)/b)], f, t]  

Mathematica simply spits back the same input.

thanks
Matt
