Floor plan

In architecture and building engineering, a floor plan is a drawing to scale, showing a view from above, of the relationships between rooms, spaces and other physical features at one level of a structure.

Dimensions are usually drawn between the walls to specify room sizes and wall lengths. Floor plans may also include details of fixtures like sinks, water heaters, furnaces, etc. Floor plans may include notes for construction to specify finishes, construction methods, or symbols for electrical items.

It is also called a plan which is a measured plane typically projected at the floor height of 4 ft (1.2 m), as opposed to an elevation which is a measured plane projected from the side of a building, along its height, or a section or cross section where a building, is cut along an axis to reveal the interior structure.

Overview

Similar to a map the orientation of the view is downward from above, but unlike a conventional map, a plan is drawn at a particular vertical position (commonly at about 4 feet above the floor). Objects below this level are seen, objects at this level are shown 'cut' in plan-section, and objects above this vertical position within the structure are omitted or shown dashed. Plan view or planform is defined as a vertical orthographic projection of an object on a horizontal plane, like a map.

42nd Street Shuttle

The 42nd Street Shuttle is a New York City Subway shuttle train service that operates in Manhattan. Part of a former Interborough Rapid Transit Company (IRT) line, it is sometimes referred to as the Grand Central / Times Square Shuttle, since these are the only two stations served by the shuttle. It runs at all times except late nights, connecting Times Square to Grand Central under 42nd Street. It is the shortest regular service in the system, running about 3,000 feet (910 m) in under two minutes. The 42nd Street Shuttle is part of the A Division of New York City Transit, and the tracks that it uses opened in 1904 as part of the first subway in the city. In order to distinguish it from the other shuttles in the system, NYCT Rapid Transit Operations internally refers to it as the 0 (zero). It has no above-ground stations, making it the only IRT service to remain completely underground during its entire run. Its route bullet is colored dark slate gray on route signs, station signs, rolling stock, and the official subway map.

Audio signal

An audio signal is a representation of sound, typically as an electrical voltage. Audio signals have frequencies in the audio frequency range of roughly 20 to 20,000 Hz (the limits of human hearing). Audio signals may be synthesized directly, or may originate at a transducer such as a microphone, musical instrument pickup, phonograph cartridge, or tape head. Loudspeakers or headphones convert an electrical audio signal into sound. Digital representations of audio signals exist in a variety of formats.

An audio channel or audio track is an audio signal communications channel in a storage device, used in operations such as multi-track recording and sound reinforcement.

Signal flow

Signal flow is the path an audio signal will take from source (microphone) to the speaker or recording device. It is most frequently in a recording studio setting, where the signal flow is often very long and convoluted as the electric signal may pass through many sections of a large analog console, external audio equipment, and even different rooms.

Price channels

A price channel is a pair of parallel trend lines that form a chart pattern for a stock or commodity. Channels may be horizontal, ascending or descending. When prices pass through and stay through a trendline representing support or resistance, the trend is said to be broken and there is a "breakout".

Channel 70

Channel 70 was removed from television use in 1983, but was formerly used by television stations in North America which broadcast on 806-812 MHz. In the United States, channels 70-83 served primarily as a "translator band" containing repeater transmitters to fill gaps in coverage for existing stations. Many are now defunct, the rest were to have been moved to lower frequencies:
