Abstract: The correlation and demodulation circuit (6) in particular for a pseudo-random code radio-frequency signal receiver (1) includes a correlation stage (7) connected to a microprocessor (12) in particular for configuring the correlation stage in normal operating mode or in test mode. In normal operation the stage receives intermediate signals (IF) corresponding to the radio-frequency signals shaped in means (3) for receiving the modulated signals from the receiver.
