Abstract
In a method for determining filter coefficients of a digital filter, particularly in UMTS, the predetermined filter coefficients bv are divided by a same scaling factor s and then quantized in that counted from the most significant bit onwards only a certain number n of '1' bits is used and in that the quantization error E(s) is minimized by the selection of the scaling factor s0 and these scaled and quantized filter coefficients βv are implemented in the filter.
