|Knowledge Base - Glossary of Terms|
|Glossary is usually defined as an alphabetical list of technical terms in some specialized field of knowledge. This knowledge base glossary provides a collection of knowledge base documents that define many technical terms. These terms are arranged alphabetically, but you can quickly jump to a specific term by selecting its first letter from the index of the knowledge base glossary below.|

Bell-shaped cosine window optimized to minimize the maximum (nearest) side lobe. Recommended for use when your signal content consists of closely spaced sine waves.
Bell-shaped cosine window typically used to analyze continuous signals. Recommended for use when your signal content contains sine waves, a combination of sine waves, vibration data consisting of narrowband random signals, or unknown content.
The visible parts for a computer system, such as the circuit boards, chassis, enclosures, peripherals, cables and so on. It does not include data or computer programs.
Harmonic Distortion (HB)
A form of distortion in analog circuits in which harmonics (signals whose frequency is an integer multiple of the input signal) are generated. Measured in decibels (dB), harmonic distortion is calculated as the ration of a single harmonic to the level of the original signal. Also related is total harmonic distortion (THD), the ration of the sum of multiple harmonics to the level of the original signal.
A numbering system to base 16
High Level Language
A program used to simplify the creation of computer code. Allows the specification of a computer action using a smaller number of steps than assembly language.
High Pass Filter
An operation that emphasizes details in an image (image processing) or an operation that attenuates low frequency components of an analog signal (data acquisition).
The graphical representation of the gray scale occupancy of an image. With the horizontal axis representing gray level and the vertical axis representing number of pixels, the histogram graphically presents image contrast and brightness dynamic range.
The blanking signal that is produced at the end of each scanning line.
The portion of a video signal indicating the end of a line of video information. This sync pulse is used by video equipment in order to maintain line synchronization with the incoming video signal.
