The MTDSC Experiment and Deconvolution Procedure

DSC experiment (see below). The averaged signal is subtracted from the raw data and the modulation is then analysed using a Fourier transform procedure to obtain the amplitude and phase difference of the heat flow response at the frequency of the imposed modulation. 

In contrast to the very simple treatment outlined above in section 2.1, one can allow for the situation that the heat flow modulation might not always follow exactly the cosine modulation in the heating rate (for reasons that will become clear in the discussions on various transitions). Thus, the heat flow may lag behind. 

The basic output from the first stage of the deconvolution procedure is therefore, 

Having obtained the amplitudes of the modulations in heating rate and heat flow, the next step is to use these quantities to calculate a value for the heat capacity as in Eq. (11). 

There are then two alternative ways of proceeding with the deconvolution - both of which were originally proposed by Reading and co-workers [2-5 ].
