Abstract

A digital circuit for use in processing signals from ultrasonic sensors consisting of a two-dimensional filter, specially designed for ultrasonic processing applications, having a longitudinal filter 21, a transverse filter 22, an interface with the CPU 20, an address generator 23 and two maximum detectors 24 and 25, the longitudinal filter 21 having 16 stages and the transverse filter 22 having 12 stages, both with programmable coefficients and able to process data from up to 8 sensors, detecting the position and maximum value within the data flow for each sensor by means of the programmable maximum detectors 24 and 24, using data from an external memory where the results of the longitudinal filter are stored.
