Abstract
An analog-to-digital converter is disclosed providing high speed operation or high resolution analog signal data. The converter utilizes the repetitive nature of the data by converting a portion of the signal corresponding to the changing component of the data. A smaller number of bits of information is thus converted from analog-to-digital form than is needed to represent the data. In addition to savings in hardware, a significant saving in conversion time is provided. The cancellation of static components of a radar signal moreover provides, within the system, a clutter-free signal.
