ABSTRACT:
An output circuit for use with an array of analog energy detectors includes a system for digital companding which is capable of providing output signals with an enhanced dynamic range. A digital compressor is provided for converting the output signals of the analog detectors into compressed digital values. Accumulators are provided for holding the output signals of the digital compressor. An expander is provided to expand the digital output signals held in the accumulators to determine the energy patterns impinging on the array of analog detectors.
