Abstract:
A method of processing first and second signals obtained by measuring a medium, to obtain a pulse wave signal and an artifact signal which are separated, includes: separating vectors of the first and second signals by using a separation matrix into a vector of the pulse wave signal and a vector of the artifact signal, the separation matrix including a norm ratio of a stable zone of the pulse wave signal and a compensated norm ratio of an artifact zone.
