Title: Echo sounder system with electronic storage - uses ram and counter instead of shift register to reduce access time
Inventor: DOBRITZ GUENTER DIPL ING
IPC: G01S7/56
Filed: 1977-03-30
Abstract: The echo sounder with electronic storage uses a binary shift register to store the echo information which is then read out to a visual display unit after digital-analogue conversion. Instead of a conventional shift register, a random access memory is used which gives faster access times, lower consumption and is smaller and cheaper. The RAM is used in conjunction with a counter to operate as a shift register. The RAM has 64 columns and lines so that it contains 64 echo signals. The binary (11) feeds the row selector of the RAM. A binary counter is controlled by a divide-by-five stage (25) so that it is switched to a new column after the 5th step so that the echo signal is transferred to the display tube five times in succession. Thus a second shift register can be dispensed with.
