I am not shure, if my CW-.filter(s) work(s) correctly because I find
it/them rather broad regarding the shape factor. If the peak-width is
set to approx. 150 Hz (0,20) the -6 db-width is around 200 Hz, but the -
60 db-width is still about 1,6 khz. I don´t have precise measurement
tools, so don´t take the stated values as absolute values, but I can´t
be too far off. I wonder if I have built in a mistake and - if yes -
with what method I can trace ist.
Has anybody checked the shapefactor of the CW-filter-chain at different
settings?
