of the operations. For example, if the first
operation in a sequential program produces a
result that is an operand of the second oper-
ation of the program, that second operation
cannot be performed until the first operation
has been completed, since its operand value
will not be available earlier.
dependent source See controlled source.
depleted uranium uranium in which the
proportion of fissile U-235 has been reduced
below useful levels.
depletion layer space charge region or
layer adjacent to a semiconductor junction
where the majority carrier concentration has
been depleted or reduced below the thermal
equilibrium value.
depletion mode an FET that is on when
zero volts bias is applied from gate to source.
depolarization (1) the change of the po-
larizationstateofawavepropagatingthrough
an anisotropic medium.
(2) phenomenon that occurs when a wave
becomes partially or completely unpolarized.
(3) changing the original polarization of a
propagating wave into a different type.
depolarizing scattering change in the po-
larization of the light due to strong scattering.
deposited multi-chip module (MCM-D)
a multi-chip module built using the deposi-
tion and thin-film lithography techniques that
are similar to those used in integrated circuit
manufacturing.
depth in computer vision, the distance to a
surface, as perceived subjectively by the ob-
server. Also, the number of bits with which
each pixel is represented in a digital image.
depth map a map of depth in a scene cor-
responding to each pair of coordinates in an
image of the scene.
