Line 7:
A '''sampler''' is a subsystem or operation that extracts samples from a [[continuous signal]]. A theoretical '''ideal sampler''' produces samples equivalent to the instantaneous value of the continuous signal at the desired points.
 
The original signal can be reconstructed from a sequence of samples, up to the [[Nyquist limit]], by passing the sequence of samples through a type of [[low-pass filter]] called a [[reconstruction filter]].
