db - Abbreviation for decibel(s). See decibel.
db LOSS - The loss of signal over a path or conductor, expressed in decibels.
DC - Abbreviation for direct current. See direct current. Also abbreviated dc.
DCR - Abbreviation for direct current resistance. The resistance offered by any circuit to the flow of direct current.
DEC - Abbreviation for Digitial Equipment Corporation.
DECA - A prefix to a unit, denoting a multiple of ten (10) of that unit.
DECI - A prefix to a unit, denoting a sub­multiple of one-tenth (10 -1) of that unit.
DECIBEL - A unit used to express ratios of sound or signal power, defined by the following formula where n is the number of decibels.
n = 10 log10 ( P2 / P1 )
Where P1 and P2 are the power levels. Since decibels represent a ratio, it is necessary to establish a refer- ence level in order to indicate an absolute level. For sound, the reference level is a pressure of 0.0002 microbar. Abbreviated as db.
DEGREE RISE - The amount of increase in temperature caused by the introduction of electricity into a unit.
DELAY LINE - A conductor that is made of a specific material in a specific size and length that will permit the delay of an electrical impulse for a predetermined specific length of time. The delay is measured in microseconds or nanoseconds.
DENSITY - The distribution of a quantity (as mass, electricity, or energy) per unit, usually of space.
DESICCANT - Water or moisture absorbent material used to prevent moisture from damaging packaged equipment or other merchandise.
