The current Cutler Naval Station was built during 1960 and became operational on January 4, 1961. It has a transmission power of 2 megawatts. As with all VLF stations, the transmitter has a very small bandwidth, and so cannot transmit audio (speech) but only coded text messages, at a relatively low data rate.
It is an improvement on the General Motors GM-NAA I/O operating system, the first operating system for the IBM 704. The main objective was to improve the sharing of programs. The SHARE Operating System provided new methods to manage buffers and input/output devices. Like GM-NAA I/O, it allowed execution of programs written in assembly language.
The GM-NAA I/O input/output system of General Motors and North American Aviation was the first operating system for the IBM 704 computer. [1] [2] It was created in 1956 by Robert L. Patrick of General Motors Research and Owen Mock of North American Aviation. [1] It was based on a system monitor created in 1955 by programmers of General Motors ...
† Although the mic input is usually mono, the input is still a TRS phone socket. Many mono 'computer' mics are fitted with TRS plugs. The tip is for the MIC and the ring is for power (to power an electret-condenser style MIC). There are exceptions to the above: Hosa cables use grey and orange for left and right analogue channels.
Direct Stream Digital (DSD) is a trademark used by Sony and Philips for their system for digitally encoding audio signals for the Super Audio CD (SACD).. DSD uses delta-sigma modulation, a form of pulse-density modulation encoding, a technique to represent audio signals in digital format, a sequence of single-bit values at a sampling rate of 2.8224 MHz.
The word select clock changes one bit clock period before the MSB is transmitted. This enables, for example, the receiver to store the previous word and clear the input for the next. [1] Data is signed, encoded as two's complement with the MSB (most significant bit) first. [1]
A digital pen is an input device which captures the handwriting or brush strokes of a user, converts handwritten analog information created using "pen and paper" into digital data, enabling the data to be utilized in various applications. For example, the writing data can be digitized and uploaded to a computer and displayed on its monitor.
A composite monitor or composite video monitor is any analog video display that receives input in the form of an analog composite video signal to a defined specification. [1] A composite video signal encodes all information on a single conductor; a composite cable has a single live conductor plus earth.
