1. A system for quantizing a vector corresponding to an input signal, the vector having a plurality of components corresponding to an N-dimensional space, the system comprising: a first part of at least one of a digital to analog converter (DAC) circuit and an analog to digital converter (ADC) circuit, the first part including at least one tree including a plurality of nodes, the plurality of nodes corresponding to a plurality of ANDs of a plurality of comparisons between the plurality of components, each comparison of the plurality of comparisons determining whether a first component of the plurality of components is greater than a second component of the plurality of components; and a second part of one of the DAC circuit and the ADC circuit, the second part including logic for asynchronously traversing the at least one tree to determine a closest match to the vector.
