Abstract
A processor disposed over a substrate of an electronic apparatus acquires a first measured value from a temperature sensor disposed on the substrate, and calculates surface temperature of a surface of an enclosure of the electronic apparatus on the basis of a transfer function G(s) based on a first thermal resistance and a first thermal capacitance between a heat source over the substrate and the surface of the enclosure, a transfer function H(s) based on a second thermal resistance and a second thermal capacitance between the heat source and the temperature sensor, and the first measured value.
