In order to evaluate the noise reduction performance of various linear filters
we propose a new formula to calculate their output signal to noise（ANR）and use a unified approach to derive the minimum up bound of linear filters’output SNR.It is applicable to any kinds of input signals:the power limited signals
the energy limited signals
the known signals
and the random signals.We also demonstrate that the often used Wiener Filter and Match Filter
