1. A circuit for determining a best fit to input signals with a selected set of basis functions ε

  • k, which are signal functions of a preselected variable, said circuit comprising;

    an N plurality of gain-providing amplifiers, where N is a chosen number with each amplifier Ai having an input terminal and output terminal; and

    conductance devices of conductance value Tij, with each conductance device connecting said output terminal of amplifier Ai to the input terminal of amplifier Aj, i and j being subscripts that denote a particular of said amplifiers and conductance devices whereineach of said conductance values Tij is related to the dot product of the ith basis function ε

    i and the jth basis function ε

    j.
