  • Abstract
    Comb filters with tunable passband characteristics have been achieved using a muItitap surface-wave delay line with electronic phase-shifting circuits in the feedback loop. The results are obtained either by summing the acoustic signals on the substrate or by using electronic summers. Q´s ranging from 500 to 50 000 have been measured for the surface-wave comb filters.
