Abstract
An ultrasonic system includes a recurrent pulse emitter including an intercorrelation circuit for determining blood flow profiles. Three filters in parallel eliminate fixed echoes with passband and delay lines, the passbands of which filters are juxtaposed. Amplitude detectors connected to the input of a comparator detect the filter output signals amplitude and delay elements are connected between the output of each filter and a multiplexor, the latter receiving a control signal (CO) issued by the comparator to select at its output that one among the output signals of the filters which presents the highest amplitude.
