Time-Frequency Analysis of Brain Electrical Activity Adaptive Approximations

OBJECTIVES: We present an approach to time-frequency analysis of bioelectrical signals. METHODS: The method relays on the decomposition of the signal into a set of waveforms that have good localization both in time and in frequency...
