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????

Answer Posted / amit
we cannot recover the signal although the sample rate >twice
the max freg .because at zero amplitude it contain the DC
value.means no information
