Angstrom - An angstrom, angström, or ångström (symbol Å) is a unit of length. It is not an SI unit. It is accepted (although discouraged) for use with the SI. It is used sometimes used expressing the size of ato. Used Audio. ms, and lengths of chemical bonds and visible-light spectra.
The ångström is named after the Swedish physicist Anders Jonas Ångström (1814–1874), one of the founders of spec. Used Audio. troscopy. Besides astrophysics, Ångström was also a student of heat transfer, terrestrial magnetism, and the aurora borealis, which was so prominent for him in his northern skies. He created a spectrum chart of sol...
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...
Multi Effects - Multi effects applies to any outboard audio effects hardware that is capable of processing the signal through more than one effect. In modern effects hardware multi effects are more common and usuall. Used Audio. y include many different effects by which the audio can be processed.. Used Audio. ...
Active - A active circuit works with an external power supply and usually at low power. A passive circuit operates directly on a signal using the power coming from the surrounding circuitry.
This is the . Used Audio. reason why an active crossover is, for the most part, placed before amps, containing integrated circuits (and line level signal processing). On the other hand a passive crossover is pl. Used Audio. aced after amplifiers where power levels are much larger . ...
Alternating Current - An alternating current (AC) is an electrical current where the magnitude and direction of the current varies cyclically, as opposed to direct current, where the direction of the current stays constan. Used Audio. t. The usual waveform of an AC power circuit is a sine wave, as this results in the most efficient transmission of energy. However in certain applications different waveforms are used, s. Used Audio. uch as triangular or square waves.
Used generically, AC refers to the form in which electricity is delivered to businesses and residences. However, audio and radio signals carried on electrical wire ar
