Ideal sampling: reconstruction
nReconstruction is obtained by
lowpass filtering. Assume the ideal lowpass filter with
the respective impulse response is therefore
nDue
to the translations
the respective impulse response is therefore
nIn
ideal sampling reconstruction weighted impulse train (representing the
sampled signal) is applied to this filter and the output is
