This method causes evolution of the thermal properties of the calorimeter as a function of time. In this paper it is shown that identification and deconvolution of the thermal signal are equivalent problems when dealing with time-varying systems. A signal treatment analysis is proposed based upon optimal tracking, and different numerical examples, where the actual calorimeter is replaced by a discrete RC model, are presented.||URI:||http://hdl.handle.net/10553/48072||ISSN:||0040-6031||DOI:||10.1016/0040-6031(86)87020-4||Source:||Thermochimica Acta [ISSN 0040-6031], v. 97, p. 203-213|
