Abstract
The power compensated differential scanning calorimetry (DSC) can be c onsidered as a linear system to a first approximation. Thus the theory of linear response is applicable to describe the apparatus. An outlin e of this mathematical tool is given. It is shown how the apparatus an d the sample and their thermal connection influence the output signal, and how to obtain the true heat flow from the measured curve with the aid of the Green's function of the apparatus and of the sample.
