Digital signal - A digital signal is a signal that is both discrete and quantized. Its primary counterpart is an analog signal. Digital signals usually occur in electronics, but may be found in other fields of enginee. Used Audio. ring as well.
Digital signals may be divided into two categories:
* Some are inherently both discrete and quantized (ex. the number of people who visit a ce. Used Audio. rtain establishment every day).
* Some describe phenomena that are actually continuous in one way or another. The signal must be discretized, quantized, or both, in order to make it digital. This "digitiz...
Cabinets - A cabinet is a loudspeaker enclosure designed to prevent sound waves from the rear of the speaker combining with the sound waves from the front of the speaker creating
interference that would c. Used Audio. ause the efficiency of the speaker to be compromised.. Used Audio. ...
Polarity - The polarity of an object is, in general, its physical alignment. The term is often used to describe the positive and negative ends of batteries and magnets.
In cell biology, polarity ref. Used Audio. ers to cells not being point-symmetrical in their spatial organization. This is particularly evident for cells organized in single cell layers that separate organs or subcompartments in . Used Audio. organisms.
In chemistry, molecular polarity refers to the dipole-dipole intermolecular forces between the slightly positive end of one molecule to the negative end of another or the same molecule. Mole...
Acoustics - Acoustics is a branch of physics and is the study of sound, mechanical waves in gases, liquids, and solids. A scientist who works in the field of acoustics is an acoustician. The application of acoust. Used Audio. ics in technology is called acoustical engineering. There is often much overlap and interaction between the interests of acousticians and acoustical engineers.
"... acoustic. Used Audio. s is characterized by its reliance on combinations of physical principles drawn from other sources; and that the primary task of modern physical acoustics is to effect a fusion of the principles normally adhering t...
Ampere - The ampere (symbol: A) is the SI base unit of electrical current equal to one coulomb per second. It is named after André-Marie Ampère, one of the main discoverers of electromagnetism.
Th. Used Audio. e ampere is that constant current which, if maintained in two straight parallel conductors of infinite length, of negligible circular cross-section, and placed 1 metre apart in vacuum, w. Used Audio. ould produce between these conductors a force equal to 2×10–7 newton per metre of length....
