1. In combination:

  • a plurality of computation units serially connected to each other, each of said computation units having an input and an output and being responsive to an input signal, the output of one of said computation units being coupled to the input of the next of said computation units for forming a transformation of an input signal coupled to said one computation unit, each of said computation units comprising;

    means for storing a plurality of signals, arithmetic means connecting with an input of said computation unit and said storage means for extracting pairs of signals and forming arithmetic combinations of the signals of said pairs of signals, said arithmetic combinations being the sums and the differences of the signals of said pairs of signals, one signal of a pair of said pairs of signals being an input signal to said computation unit and the other signal of a pair of said pairs of signals being extracted from said storage means, and a feedback path coupling an output of said arithmetic means to an input of said storage means, said feedback path placing one of said arithmetic combinations in said storage means; and

    means coupled to each of said computation units for coordinating said forming of said arithmetic combinations and said placing of said one arithmetic combination in said storage means in each of said computation units in accordance with a predetermined formulation to provide said transformation.
