STOPBAND FREQUENCY CALCULATIONS:
Using part number LT9-144K-50-1335, we know
that the filter is a 9 pole Bessel lowpass filter.
Scroll down to series number LT9. Moving to the
right we find the stopband specification listed as
-60dBc minimum at 4.3 x f -3dBc. Thus, the -60dBc
frequency is at 619.2 kHz (4.3 x 144 kHz).
