In digital signal processing, downsampling, compression, and decimation are terms associated with the process of resampling in a multi-rate digital signal processing system. Both downsampling and decimation can be synonymous with compression , or they can describe an entire process of bandwidth reduction ( filtering ) and sample-rate reduction.
Sample-rate conversion prevents changes in speed and pitch that would otherwise occur when transferring recorded material between such systems. More specific types of resampling include: upsampling or upscaling ; downsampling , downscaling , or decimation ; and interpolation .
The top pair of graphs represent the discrete-time Fourier transform (DTFT) representation. The middle pair, depict a normalized frequency scale, preferred by many filter design programs. The frequency, f, in Hz is divided by the sample-rate. The periodicity and Nyquist frequency are then represented by constants, 1 and 1/2 respectively.

Enterprise modelling is the process of building models of whole or part of an enterprise with process models, data models, resource models and/or new ontologies etc. It is based on knowledge about the enterprise, previous models and/or reference models as well as domain ontologies using model representation languages.

The end of the holiday weekend added two fresh examples of a historic shift on Wall Street: More CEOs than ever are heading for the exits. Over the past 24 hours, the leaders of chipmaker Intel ...
For example, if compact disc audio at 44,100 samples/second is upsampled by a factor of 5/4, the resulting sample-rate is 55,125.
