A binary-decimal code for transmitting signals of telemetry, which relieves the need for carrying out a great deal of conversions on the reception side, is proposed. In the code- pulse system of telemetry with a pickup in the form of a photoconverter for assuring the discreteness the rotatable disk is perforated for the binary code. In order to avoid gross errors in remote transmission a code with a minimul of error is selected, such as Grays code. In the described binary-decimal code the numbers of each decimal category are expressed by a four-category binary code-the tetrad. As a decimal code, in contrast to the direct decimal counting a reflex code Grays code is used.
