AbstractRemote-control installations are generally operated by an audio-frequency tone on a radio-frequency carrier. A different modulating frequency is necessary for each channel or remote operation. A system is now being developed which uses a seven-bit binary code number for each channel. In order to utilize the conventional radiotelegraph transmitter presently installed in ships at sea the binary numbers 0 and 1 were converted to dots and dashes. The circuit described in this report distinguishes the received dots from dashes and produces pulses at two separate outputs.
