Glossary of Terms
ADC
Analog-to-Digital conversion is an electronic process in which a continuously variable (analog) signal
is changed, without altering its essential content, into digital data.
Bandwidth
Describes the measure of data transfer capacity. A computer system’s PCI expansion bus is rated for a
maximum peak data bandwidth of 132 MB/s. PCI devices must share the maximum PCI bus
bandwidth when transferring data to and from system memory or other devices.
Bus
A common pathway, or channel, between multiple devices. Besides the computer's internal bus to
memory and system components, peripheral buses such as PCI and AGP, allow adding or changing
devices that make up the computer system.
Clamper Circuit
A circuit that establishes a fixed level for the video signal at the beginning of each scanning line.
CMRR
Common-Mode Rejection Ratio: The ratio of the common-mode noise or interference voltage at the
input of a circuit, to the corresponding noise or interference voltage at the output.
Composite Video
A video signal that is composed of the luminance and color information plus the synchronization
signals together. Common composite video formats are NTSC and PAL.
Contiguous Memory
A block of physical memory occupying consecutive addresses.
Driver
Also called a device driver, a program routine that links a peripheral device to the operating system.
Specific to the Bandit-II, its VGA driver is required for its display adapter functionality and a device
driver is required for its frame grabber capabilities.
Frame
One complete image data set or its equivalent storage space.
