Abstract
A system for accurately merging data signals generated by two spaced apart multi-element MICR read heads is provided. Digital data signals are sampled near the signal peaks, converted to NRZ (non-return-to-zero) data and synchronized to a common fixed frequency. The digital data signals then are serialized to form two digital data streams, each of which corresponds to the responses of one of the two read heads. Phase differences between the two data streams are detected and corrected. In accordance with the invention, the data streams are interlaced to form a single digital data stream accurately representative of the information field sensed by the MICR read heads.
