A line array is a loudspeaker system that is made up of a number of usually identical loudspeaker elements mounted in a line and fed in phase, to create a near-line source of sound. The distance between adjacent drivers is close enough that they constructively interfere with each other to send sound waves farther than traditional horn-loaded ...

Commercially, this type of loudspeaker arrangement is known as a line array. This technique has been around for many years but since the emergence of modern digital signal processing (DSP) technology there are now many commercially available products on the market. Beam steering and directivity Control using DSP was pioneered in the early 1990s ...
Array processing is a wide area of research in the field of signal processing that extends from the simplest form of 1 dimensional line arrays to 2 and 3 dimensional array geometries. Array structure can be defined as a set of sensors that are spatially separated, e.g. radio antenna and seismic arrays .
Thunderbolt (interface) also supports daisy-chained devices such as RAID arrays and computer monitors. [3] DisplayPort 1.2 and higher features Multi-Stream Transport (MST) mode. In this mode, multiple screens can be connected either using a hub or as a daisy chain. The Hexbus is the 10-wire bus of Texas Instruments, used in the TI-99/4A, CC-40 ...

The most common form of log-periodic antenna is the log-periodic dipole array or LPDA, The LPDA consists of a number of half-wave dipole driven elements of gradually increasing length, each consisting of a pair of metal rods. The dipoles are mounted close together in a line, connected in parallel to the feedline with alternating phase.
In order for the signals to add together, they need to arrive in-phase.Consider two dipole antennas placed in a line end-to-end, or collinear.If the resulting array is pointed directly at the source signal, both dipoles will see the same instantaneous signal, and thus their reception will be in-phase.
