Suppose there is a SAS dataset with following values -
Parent Child
A B
B C
D E
F G
G H
H I
and so on…..
This goes onto 1000s of observations/rows.
Now how do we identify from this dataset Grandparents and
Grandchildrens ?
interviewr asked about sampling theorem and i said the
common def.(i.e ...sam freq must >=s max freq in the signal
for a sampled signal to recover without alising).he asked
that i have a sin signal of freq 1hz and i sampled at two
zero amplitude points can it be recoverable without
aliasing????
