1. A system for digitally storing samples of the amplitude of an analog signal, such samples being taken at a constant sampling frequency, f, comprising:

  • (a) a plurality of, n, digital storage means, each one being fed, in parallel, by the analog signal and each one being adapted to store a train of samples of the amplitude of the analog signal fed thereto in response to a train of sampling pulses fed to such one of the plurality of digital storage means;

    (b) means for producing a plurality of trains of the sampling pulses, each one of such trains of the sampling pulses having a pulse repetition frequency f/n, with the sampling pulses in the trains thereof being displaced in time, one from another, an amount 1/(nf); and

    ,(c) means for feeding each one of the plurality of the produced trains of the sampling pulses to a corresponding one of the plurality of digital storage means.
