摘要

热结构函数允许对电子元件的热路径流有一个深入的了解。本文分析了该技术对噪声的敏感性。为了这个目的，考虑一个均匀的材料板，因为在这种情况下确切的时间常数谱是已知的。结果表明，热瞬态过程中热结构函数对噪声非常敏感

Difficulties on the estimation of the thermal structure function from noisy thermal impedance transients

The thermal structure function permits to have an insight in the thermal pathflow of electronic components. In this work the sensitivity to noise of this technique is analyzed. For this purpose, a homogeneous slab of material is considered, since for this case the exact time constant spectrum is known. Results show that the thermal structure function is very sensitive to noise in the thermal transient
