I have an equation de/dt=C1*(ds/dt)+C2*s. C1,C2=constants, e=strain, s=stress, d/dt=derivative wrt time (t). I want to convert it in frequency signal i.e. instead of time t I wish to have frequency f. Can anyone help.

The easiest way might be to take the Laplace transform of your differential equation. The frequency content will be only along the (positive) imaginary axis, not the entire complex plane. (The symbolic Fourier transform is another option, but I have very limited experience with it, so I would not be able to help with it.)
