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 XL4. 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, suc. Used XL4. h 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
Amplifier - The amplifier can be considered to be any device that uses a small amount of energy to control a larger amount, although the term today usually refers to an electronic amplifier. The relationship of t. Used XL4. he input to the output of an amplifier — usually expressed as a function of the input frequency — is called the transfer function of the amplifier, and the magnitude of the transfer functi. Used XL4. on is termed the gain. There are numerous types of electronic amplifier depending upon the application....
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 XL4. ics in technology is called acoustical engineering. There is often much overlap and interaction between the interests of acousticians and acoustical engineers.
"... acoustics . Used XL4. 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...
Subs - A sub or subwoofer is a speaker dedicated to the reproduction of bass frequencies, usually from about 20 Hz to about 200 Hz. . Used XL4. . Used XL4. ...
