Dynamic range — For other uses, see Dynamic range (disambiguation). Dynamic range, abbreviated DR or DNR,[1] is the ratio between the largest and smallest possible values of a changeable quantity, such as in sound and light. It is measured as a ratio, or as a… … Wikipedia
Full-range — A Full range loudspeaker drive unit is defined as a driver which reproduces as much of the audible frequency range as possible, with high fidelity, within the boundaries imposed by the physical limitations of the specific design. This is so… … Wikipedia
Audio frequency — An audio frequency (abbreviation: AF), or audible frequency is characterized as a periodic vibration whose frequency is audible to the average human. While the range of frequencies that any individual can hear is largely related to environmental… … Wikipedia
Beat frequency oscillator — A beat frequency oscillator or BFO in radio telegraphy, is a dedicated oscillator used to create an audio frequency signal from carrier wave transmissions to make them audible, as they are not broadcast as such. The signal from the BFO is then… … Wikipedia
