http://www.w3.org/ns/prov#value | - The LPF 104 in the wobble signal extractor 22 suppresses or attenuates the spike-like peaks and the spike-like valleys in the amplification-resultant signal SPPX. In this way, the limiter 101 and the LPF 104 process the amplification-resultant signal SPPX into the LPF-resultant signal SL which has a waveform such as shown in FIG. 7.
