Filed: 1990-02-15
Abstract: PURPOSE:To minimize a detection error by providing a frequency conversion filter converting a sampling frequency into a specific frequency and a detection means identifying a detected frequency signal from a data resulting from the conversion. CONSTITUTION:A digital signal processor 1 is provided with a band pass filter 10, a sampling frequency conversion filter 12 an a detection section 14.
