Abstract
An improved analog to digital converter of the parallel or series-parallel type having expanded range for a given number of comparators in the quantizer. The converter is particularly adapted to convert analog signals, such as television signals, of a type in which a large percentage of the time the analog signal falls within only a portion of the predetermined full range. The quantizer is capable of converting only signals within the portion of the full range. Switching circuitry having a hysteresis characteristic shifts the effective range of the quantizer to additional overlapping ranges to permit conversion of signals outside the portion of the predetermined range.
