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 / puneet kapil

We cannot recover the signal although sampled rate is twice the source frequency without aliasing because at zero amplitudes. because it is an ambiguity in sampling theorem that for θ for which sin(θ)= 0, its not applicable this is called critical frequency points in source signal.

Answer / 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

Answer / sivareddy6085

plese give me answers?(i think we have to take samples at
non zero points)

Answer / your friend

i suppose there will be no aliasing since sampling is done
at twice the source frequency but seems signal can not be
recovered because mapping done between the samples (using
any order) can go any amplitude.
