Correlation apparatus

摘要

This invention relates to a pattern recognition correlator in which a serial input data signal is converted into a parallel data signal for correlation with one or more reference data signals. The invention relates to use of a demultiplexer in such a correlation apparatus to reduce the data update rate for the subsequent components. The invention also relates to the use of a series of latch circuits to provide serial to parallel conversion of the input data signal in the electrical domain.
