oscillations by the myriad
the two crossings are one period
only white noise will remain
if all the numbers are the same

I just do the operation twice
producing a bilinear cubic splice
and the result, you can see
is simply cosine omega t

all these numbers are binary
keep delta x primary
since one byte is eight bits
you can calculate the hits

the relation between correlation index one
and the total zero crossing sum
connects the time and spectral domain
in the orthographic plane
