Andy,
This filter is shown in the LF Experimenters Handbook on page 25, as part
of
the outline design for a narrow bandwidth LF receiver. The frequency
response I measured is given on page 26
A step change causes it to ring for a few cycles
Thanks for the info - looks good!. I'll read that article tonight (must have
missed it) and also check out the filter on the bench as soon as I can pick
up the xtals.
Bill A
