Hello,

I just measured the resonance frequency of ten 10 MHz crystals. I
found a
set of four within 30 Hz and another set of four within 45 Hz.

How does this compare to other peoples results?

Did somebody already plot the passband shape of a resulting 4 crystal
filter?
How do you do that? Figure out the shape that is?

Tnx
