[QUOTE="Phillip Pietruschka, post: 206521, member: 7640"] I've been having some discussions with Michael about his software via email, and he has been very helpful. He suggested bringing some of the discussion into a public forum so others can participate. So one of the points of discussion with Michael was about using Complex or Power based magnitude averaging for smoothing imported traces. I am used to using power based averaging when using smaart to tune a system in situ. I am curious to hear from anyone who thinks complex averaging may be better suited to the needs task of FIR filter design. I am used to looking at power based averages, and when using complex averages and broad bandwidth averages Ive been able to generate so initially counter intuitive results (where a big dip in the mag response appears where there is no dip at a higher resolution). I'd also been to hear from Michael about the 'use coherence' function. I assume this uses the coherence value to weight each data point in the smoothing. However, you know what they say about assumptions... Best, Phillip [/QUOTE]
