Properties of the convection zone are encrypted in the behavior of acoustic modes (p modes) and also in the excitation mechanism. The goal of this study is to reconstruct the pattern of the excitation (e.g., the rate and strength of the excitation) from an observed signal. The method, homomorphic deconvolution, has been tested on several sets of artificial signals. The preliminary results presented here are promising. Further rigorous tests and the eventual application to a real signal will be carried out in the near future.
