ABSTRACT:
In an echo sounder including a cathode-ray tube display device for providing a visual display in the form of a succession of image frames each composed of a series of image lines extending in a first direction on the display and spaced apart in a second direction on the display, with each line being composed of a plurality of image points, and a memory having a number of addressable memory locations equal to at least the number of image points in each frame, with a representation of each image point being stored at a respective memory location, the memory is an addressable read-write random access memory, and the device includes circuitry connected for causing each memory location address to consist of a first part identifying the location of one image line in the second direction on the display and a second part identifying the location of one image point along any line in the first direction on the display, an address counter producing an output representing the address part corresponding to one direction, a sounding period counter connected to operate in synchronism with the address counter and producing a count output representing the address part corresponding to the other direction, and write-in control elements connected for producing a write-in control signal which causes the memory to be addressed by the counter outputs and a received signal sample to be written-in to the addressed memory location during each line or frame retrace period.
