Abstract
Analog phase-shift elements connect each of a plurality of input nodes to each of a plurality of output nodes, wherein each component is adapted to produce a phase shift in a periodic signal processed therethrough. A linear transformation of a data set of discrete values of a given function provided as a set of analog signals to the input nodes is achieved by judiciously adjusting the signal amplitude produced at the output of the phase-shift components and summing the resulting output signals as required to simulate the transformation of interest.
