Time-Frequency Analysis of the Auditory Brainstem Response

I would like to thank my supervisor Maria Sandsten for her great support and guidance. Her ideas and helpful advice have been invaluable. Most of my work has been done at the Centre of Mathematical Sciences at Lund Institute of Technology from April through summer and early autumn. I would also like to thank SensoDetect AB, and Johan Källstrand in particular for giving me data to analyse. This thesis is about time-frequency analysis of the brainstem auditory evoked potential (BAEP). The work can be divided into two parts. One part where a model is built up from a very simple example to a more complex model resulting in a model consisting of a sum of sinusoids with stochastic starting points and amplitudes. Different time-frequency methods have been eval-uated for these models and the multi window spectrogram with Hermitian base functions performs the best in a real life situation with more than one component and a high level of noise
