Abstract :
Using time-frequency representation based on the Wigner distribution gives an window-independent formulation of the signal´s energy localized in time and frequency. Thus a time-frequency region of interest can be found for transient visual evoked responses. The information is used to construct a linear time-varying filter for post-processing of visual evoked responses. The filter is constructed via the window-independent Weyl correspondence
