1. A sensor array system comprising:
- a plurality of sensors;
a plurality of inputs, each for receiving a signal from a respective one of the plurality of sensors;
one or more outputs for outputting signals derived using the signals from said inputs;
a plurality of sparse filters each coupled between an input and an output for filtering the sensor signal received at the coupled input; and
one or more integrators coupled to one or more of said sparse filters for integrating a signal output from the coupled sparse filter and to provide the integrated signal to the corresponding output.

Abstract
A control system is provided for controlling a transducer array. The control system includes a plurality of sparse filters and integrators. The control system can be used to separate signals from a plurality of sources or to generate complex signal patterns that combine and map to different spatial regions.
