Abstract:
1. A quantizer, comprising a plurality of calculation blocks, wherein at least one of the calculation blocks comprises: a comparator, for comparing an input value with a respective threshold value; a threshold calculator, for forming a new respective threshold value from the respective threshold value and a respective increment value, based on a result of the comparison of the input value with the respective threshold value, such that the new respective threshold value is used as the respective threshold value in a subsequent calculation block; and an output, for providing an output bit based on the result of the comparison of the input value with the respective threshold value, and wherein a final calculation block comprises: a comparator, for comparing the input value with a respective threshold value; and an output, for providing an output bit based on the result of the comparison of the input value with the respective threshold value, the quantizer further comprising an increment calculation block, for forming the respective increment value.
