  • Patent number: 7010075
    Abstract: A sampling system includes a first sampler which periodically samples an input signal at a fixed sampling period T to output a sequence of samples. A first lowpass filter outputs a sequence of ?T/4 phase shifted samples from the sequence of samples. A second lowpass filter outputs a sequence of +T/4 phase shifted samples from the sequence of samples. A second sampler outputs a sequence of secondary samples by alternately taking the ?T/4 phase shifted samples supplied by the first lowpass filter and the +T/4 phase shifted samples supplied by the second lowpass filter at,a sampling period that is half the sampling period T, the second sampler doubling the number of the samples output by the first sampler. An interpolation circuit outputs at the sampling period T a sequence of output samples by executing an interpolation of the sequence of secondary samples output by the second sampler, the sequence of output samples having a timing phase synchronized to a given arbitrary clock signal.
