An "event-synchronous interference canceller" (ESC) for cancellation of electrocardiographic (ECG) interference in diaphragmatic electromyographic (EMGdi) signals is addressed in this paper. ESC pursues the concept of the "event synchronous adaptive interference canceller" (ESAIC), which was proposed in [1] as a specific application of the well known(More)
Accurate onset detection of the voluntary response is a prerequisite in reaction time studies when used in investigations on human motor control. The detection algorithm required performs a transformation of the continuous physical signal (e.g., force, movement) containing the response into a discrete event from which the reaction time (RT) is derived.(More)
It is well known that conventional design techniques of filter banks lose their ability to guarantee the perfect reconstruction condition when additive noise disturbs the subband sequences. The alternative synthesis scheme compensates the effects of the subband noise by estimating the transmitted samples minimizing the reconstruction mean squarred error,(More)
Filter banks proved to be effective in many signal processing contexts. A method to improve and to enlarge the set of filter banks applications consists in overcoming the effects of developing the perfect reconstruction condition without considering distortions inducted, inevitable, by quantization and transmission over additive noise disturbed channels.

Nonlinear filtering based on the Volterra series expansion is a powerful universal tool in signal processing. Due to the problem of increased complexity for higher orders and filter lengths, approximations up to third order nonlineari-ties using linear FIR-filters and multipliers have been developed earlier, called Multi Memory Decomposition (MMD). In our(More)
