Ideal sampler

In digital signal processing, an ideal sampler is a sampler that samples in an ideal fashion. It is precisely a sampler that takes a continuous signal and multiplies it by a dirac comb (aka a "delta train") that yields another continuous signal except it only takes values at discrete times (these times need not be periodic). If the values of the resulting continuous signal were measured and considered a sequence, then it becomes a discrete signal.
