Analog FIR-filter comprising an asynchronous SIGMA Delta modulator (AM) generating amplitude-discrete time-continuous pulses, a sequence of delay cells (C1 ... Cn) for delaying said amplitude-discrete time-continuous pulses and means (O1, On, S1, Sn, I1, In) for low pass filtering the delayed amplitude-discrete time-continuous pulses. |
