A system to transform an input signal presented from a sensor into a spatial sequence characteristic of the signal. An input module of the system is configured to divide the input signal into a sequence of signal values and present them in order of production to the following stage. A comparator module coupled to the input module configured to accept each element value of the sequence of signal values. The comparator module has a multiplicity of individual comparators that generate binary values assembled into a word of bits. The word value correlates the input sequence element value with a vector of reference values to effect a level crossing sampler. The assembled word value is utilized to encode a memory address. The system effects the conversion of a signal into an ordered collection of spatial values, which are the addresses of memory locations.
