A method for detecting the presence of filterköffizienten of a digital filter and a digital filter

摘要

In the case of a process for the determination of the filter coefficients of a digital filter, in particular in the case of umts, the predetermined filter coefficients b_v with the same scale factor s divided and, as a result, quantized, that the most significant bits are counted, only a certain number n of "1" - bits is used and that the quantization error e (s) by selecting the scaling factor s₀ this is minimized and scaled and quantized filter coefficient β_v be implemented in the filter.
