2. discussion In the first experiment, the input waveform is shown to be ahead of the output waveform on the RLC series circuit. When Lissajous waveforms for different frequencies were viewed in second experiments, the frequency 10 [㎑] and 30 [㎑] were approximately the same, although the phase differences were mostly 90°. < 중 략 >3. Conclusion The values of the cut-off frequency did not vary much, but bandwidth and duplex differed greatly. Perhaps that is a margin of error for each element.
