Digital correlator for signal processing system - uses control logic coupled to multiplexers and to intermediate and result memories

摘要

The correlator used to obtain a polarity correlation function, has a data shift register (1), a reference shift register (4), multiplexers (7,8) anti-valence gates (9), adders (11), an intermediate memory (12) and a memory (13) for storing the obtained results. The outputs of the anti-valence gates (9) are coupled to the address inputs of a fixed value memory (10), their data outputs supplying 'O' bits to the adders (11). A control logic (15) is coupled via an address line (16) to the multiplexers (7,8) and via transfer signal lines (17,18) with the intermediate and result memory (12,13). Pref. the correlator uses standard microprocessor elements. USE - For discrete correlation of two digital functions.
