Abstract : A signal processing and display digital technique is described in connection with a hazard avoidance sonar system whereby data generated relatively slowly is accumulated digitally in storage and read out repetitively at a faster rate to avoid flicker on a cathode ray tube display. Logic means are provided for periodically inserting a new line of data in place of the oldest data line only, whereby a historical display is maintained while also showing progression of parameters represented by the data.
