Ideal sampler

In 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"), which yields a signal that only takes values at discrete times (these times need not be periodic).If the values of the resulting signal are measured and considered a sequence, then it becomes a discrete signal.
