Abstract :
Discusses the noise reduction performance of the linear filters and derives the minimum up bound of the linear filters´ output signal to noise ratio (SNR). It is also demonstrated that the often used winer filter, match filter, and threshold filter, derived from the different criterion, can improve the SNR
