The codes' procedure words, a type of voice procedure, are designed to convey complex information with a few words, when brevity is required but security is not. Ten-code, North American police brevity codes, including such notable ones as 10-4. Phillips Code. NOTAM Code. Wire signal, Morse Code abbreviation, also known as 92 Code.
Passband modulation. Modulated continuous wave (MCW) is Morse code telegraphy transmitted using an audio tone to modulate a carrier wave . Continuous wave (CW), by contrast, does not use a subcarrier, so there is no emission at all between Morse code symbols. MCW can be generated by any AM or FM radio transmitter with audio input from an audio ...
There are at least three sets of Z codes. 1. One set of codes was originally developed by Cable & Wireless Ltd. (the Cable & Wireless Service Z code) for commercial communications in the early days of wire and radio communications. The old C&W Z codes are not widely used today. 2. APCO [clarification needed] also developed a system of Z codes. [1]
Gradient-like vector field. In differential topology, a mathematical discipline, and more specifically in Morse theory, a gradient-like vector field is a generalization of gradient vector field . The primary motivation is as a technical tool in the construction of Morse functions, to show that one can construct a function whose critical points ...
Wheatstone system. The Wheatstone system was an automated telegraph system that replaced a human operator with machines capable of sending and recording Morse code at a consistent fast rate. [1] The system included a perforator, which prepared punched paper tape called a Wheatstone slip, a transmitter that read the tape and converted the ...
Google Translate is a web-based free-to-use translation service developed by Google in April 2006. [11] It translates multiple forms of texts and media such as words, phrases and webpages. Originally, Google Translate was released as a statistical machine translation (SMT) service. [11] The input text had to be translated into English first ...
In the Morse-code era, when Arabic language Morse signals were copied down by non-Arab code clerks, the text came out in SATTS. Text in SATTS was also automatically produced when teleprinters reproduced Arabic text, if the technician had failed to replace the printer's Latin-character pallet with an Arabic-character one.
Ten-code. Ten-codes, officially known as ten signals, are brevity codes used to represent common phrases in voice communication, particularly by US public safety officials and in citizens band (CB) radio transmissions. The police version of ten-codes is officially known as the APCO Project 14 Aural Brevity Code. [1]
