Upsampling is the process of increasing the sampling rate of a signal. For instance, upsampling raster images such as photographs means increasing the resolution of the image. The upsampling factor (commonly denoted by L) is usually an integer or a rational fraction greater than unity. This factor multiplies the sampling rate or, equivalently, divides the sampling period. For example, if compact disc audio is upsampled by a factor of 5/4 then the resulting sampling rate goes from 44,100 Hz to 55,125 Hz. The second step calls for the use of a perfect low-pass filter, which is not implementable. When choosing a realizable low-pass filter this will have to be considered and it will have aliasing effects. These aliases can be removed to a reasonable extent by a finite impulse response low pass filter. The presence of zeros in the sequence which is passed through the filter can be used to reduce the complexity of the filter implementation. The original filter can be split to L subfilters and the output of each of these subfilters is sequentially tapped to obtain the filtered output sequence.…

Etat : Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Please note that the content of this book primarily consists of articlesavailable from Wikipedia or other free sources online. In signalprocessing, downsampling (or 'subsampling') is the process of reducingthe sampling rate of a signal. This is usually done to reduce the datarate or the size of the data. The downsampling factor (commonly denotedby M) is usually an integer or a rational fraction greater than unity.This factor multiplies the sampling time or, equivalently, divides thesampling rate. For example, if compact disc audio at 44,100Hz isdownsampled to 22,050Hz before broadcasting over FM radio, the bit rateis reduced in half, from 1,411,200 bit/s to 705,600 bit/s, assuming thateach sample retains its size of 16 bits. The audio was thereforedownsampled by a factor of 2.…
