A FIR filter that is arranged to receive an analog input signal and sample the analog input signal at a plurality of discrete points in time k with a sampling frequency fS to obtain a sampled analog input signal having a continuous signal value. The FIR filter is further arranged to generate a scaled analog input signal having a continuous signal value by scaling the sampled 5 analog input signal on the basis of a plurality of scaling coefficients. The FIR filter further arranged to provide, by integration over a timed window, an integrated signal which is the sum of L scaled analog signal samples, L being an integer value, and to provide the integrated signal as an output signal from the integrator at an output rate.
