The process of changing an analog signal into a digital value that represents the magnitude of the signal at the moment of conversation.
An electronic device, often an integrated circuit, that produces a digital ouput directly proportional to an analog signal input.
A filter that removes frequencies from a signal that are higher than the cutoff frequency. When the sample rate is more than twice the cut-off frequency this filter prevents aliasing, in which low frequencies, that did not exist, appear in data after it is digitized (converted to digital) by a data acquisition device. This filter must be implemented in hardware in front of the A/D converter.
Application Programming Interface
An FRF mode that is calculated as the Force of the Reference Channel/Acceleration of the Response Channel. It is the reciprocal function of Inertance.
Arithmetic-Logic Unit (ALU)
Digital circuit used in computers to perform various arithmetic and logic operations.
Data arranged in single or multidimensional rows and columns.
American Standard Code for Information Interchange. A very popular standard method of encoding alphanumeric characters into seven or nine binary bits.
The width-to-height ratio of a video picture. An aspect ratio of 4:3 means the horizontal dimension of the image frame is 4/3 the vertical dimension.
A program that converts a list of computer instructions written in a specific assembly-language format into binary instructions that can be executed by a specific processor.
