Abstract :
Calculable AC source can be built of Josephson arrays driven by properly modulated excitation pulse stream. When Sigma-Delta modulation is used excessive high frequency noise is produced which has to be filtered out without compromising low frequency output signal. An adequate filter for this purpose was developed within a Josephson arbitrary waveform synthesizer (JAWS) project (Chevtchenko, et.al., 2004)
