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
