Decimation factor definition
WebDecimation is a term that historically means the removal of every tenth one. [a] But in signal processing, decimation by a factor of 10 actually means keeping only every tenth sample. This factor multiplies the sampling interval or, equivalently, divides the sampling … WebJun 16, 2004 · Decimation filters' architecture for an integrated power-meter is presented in this paper.

WebJul 30, 2013 · A new efficient structure for a sharpened comb factor-of decimation filter is proposed. The structure consists of two main sections: a cascade of comb filters followed by down-sampling with a factor M1 , and a sharpened comb filter followed by downsampling with a factor ,M2 where M= M1M2 .Over sampled filter banks are used to minimize … WebAfter the first decimation by a factor of two, the spectrum from f s /4 to f s /2 translates into frequencies between –f s /4 and dc. Similarly, the spectrum from –f s /2 to –f s /4 translates into the frequencies between dc and f s /4. The signal now passes through the second decimation filter, HB1, which also decimates by two (the total ...

When you are decimating a signal x (n), to x (an) (a>1),in the frequency domain the spectrum expands. This might lead to aliasing of the adjacent spectral bands.So to avoid it we use a "anti aliasing filter". Now choosing an FIR low pass filter depends on many factors like, order of the filter, attenuation in stop band, range of pass ...
