Abstract
The invention relates to high-speed correlating arrangements. Input memories receive the signals to be correlated in the form of successions of samples. At read-out of samples in the memories, the time scale of one of the signals is reversed and the two series of samples are used to modulate a wave supplied by an oscillator. The two modulated carriers are applied to an electroacoustic convolver from which, after detection and filtering, the correlation function of the input signals is obtained.
