1. A network having a first plurality of inputs coupled for receiving a spatial vector of an input signal for providing a transformation thereof at a first plurality of outputs, comprising:

  • first and second plurality of conductors;

    a plurality of weighting elements interconnected between said first plurality of conductors and said second plurality of conductors in a predetermined manner;

    a first plurality of switchable driver circuits respectively coupled between the first plurality of inputs and said first plurality of conductors, said first plurality of switchable driver circuits operating to drive said first plurality of conductors at the occurrence of a first state of a first switch control signal while receiving signals from said first plurality of conductors at the occurrence of a second state of said first switch control signal, said first plurality of switchable driver circuits including first, second and third terminals, said first terminal being coupled to one of the first plurality of inputs, said second terminal being coupled to one of said first plurality of conductors, said third terminal providing one of a first plurality of output signals;

    a second plurality of switchable driver circuits respectively coupled between the first plurality of outputs and said second plurality of conductors, said second plurality of switchable driver circuits operating to receive signals from said second plurality of conductors at the occurrence of a first state of a second switch control signal while driving said second plurality of conductors at the occurrence of a second state of said second switch control signal; and

    a switch control circuit coupled to said first and second plurality of switchable driver circuits for providing said first and second switch control signals to control the driving direction thereof.
