Suboptimal Filtering and Nonlinear Time Scale Transformation for the Analysis of Multiexponential Decays
MetadataShow full item record
Multiexponential decays may contain time-constants differing in several orders of magnitudes. In such cases, uniform sampling results in very long records featuring a high degree of oversampling at the final part of the transient. Here, we analyze a nonlinear time scale transformation to reduce the total number of samples with minimum signal distortion, achieving an important reduction of the computational cost of subsequent analyses. We propose a time-varying filter whose length is optimized for minimum mean square error.

A Time-Domain Method for the Analysis of Thermal Impedance Response Preserving the Convolution Form Carmona, Manuel; Marco, Santiago; Palacín Roca, Jordi; Samitier, Josep (Institute of Electrical and Electronics Engineers, 1999)The study of the thermal behavior of complex packages as multichip modules (MCM’s) is usually carried out by measuring the so-called thermal impedance response, that is: the transient temperature after a power step. ...
Marco, Santiago; Palacín Roca, Jordi; Samitier, Josep (Institute of Electrical and Electronics Engineers, 2001)The analysis of multiexponential decays is challenging because of their complex nature. When analyzing these signals, not only the parameters, but also the orders of the models, have to be estimated. Here, we present ...
