[MSNoise] a few questions for Filter

Dear Thomas Lecocq I am an earthquake engineer from China and I am very interested in MSnoise software. I would be very grateful if you could answer a few questions for me. 1、What's the relationship between the frequency bound (low,high) of the Whiten function(in Hz) and the frequency bound(mwcs_low,mwcs_high) of the linear regression in Filters? 2、If we want to get the seismic wave velocity changes in the range of 1-2s,2-4s,40-10s,10-25s,respectively.How to set the frequency bound (low,high) of the Whiten function(in Hz) and the frequency bound(mwcs_low,mwcs_high) of the linear regression? I look forward to your reply Yours sincerely ------------------ 祝 好 江苏省地震监测中心 王 俊 电 话 13951702501/025-84285599
