Abstract
PURPOSE:To obtain a comb filter which has flat and wide-band frequency characteristics by connecting antiresonate coils and additional capacitors in parallel to at least an input transducer of an ultrasonic-wave solid-state delay line. CONSTITUTION:To the input and output transducers 23 and 25 of an ultrasonic solid-state delay line 22, antiresonate coils 26 and 29 are connected in parallel. Then, the input transducer 23 and a voltage-dividing load 24 form a parallel circuit. This load 24 and antiresonate coil 29 constitute a pi type closed circuit. The output-side antiresonate coil 29 also constitutes a similar pi type closed circuit with a load R. To the antiresonate coils 26 and 29 of the input and output transducers 23 and 25, additional capacitors C3 and C4 are connected in parallel. Thus, a comb filter has flat and wide-band frequency characteristics extending to the high frequency range.
