Abstract

A signal processing device for determining at least one parameter of a signal, comprises: a shift register (3) arranged to receive a quantized digital signal and arranged to store temporarily a number of bits corresponding to the number of bits in a number N of samples of the quantized digital signal, memory means (7) comprising at least one look-up table (9) comprising values that may be used to determine said at least one parameter, and address means for determining at least one address of the memory means (7) to be read, in dependence of the content of the shift register (3). The table entries are determined by generating sample signals having known parameter values and determining the shift register values resulting from the sample signals, then entering suitable parameter values in the table (9) in positions corresponding to each shift register address.
