Abstract
A parallel sampling device includes a memory that stores the values of the sampling function (Sin πt/πt), a low pass filter, a sampler that samples a signal, which has passed through low pass filter, at a sampling period of Ts, and a parallel sampler provided in a stage following the sampler. The parallel sampler generates parallel sampled values at an interval of the sampling period Ts/N (N is a natural number equal to or larger than 2) based on sampled values obtained by the sampler and the values of the sampling function stored in the memory. This configuration allows parallel sampling to be performed easily even if the frequency is high or the sampling period of parallel sampling is narrow.
