Abstract: PURPOSE:To decrease the scale of the hardware by making it possible to process it in the condition that the sampling frequency is lowered, and executing time- sharing processing. CONSTITUTION:For the input signal, only discrimination signals S1-SN are taken out by a BPF12.

In other words, when the frequency of the discrimination signals is f1-fN and the sampling frequency is fS respectively, the frequency of the signals S1'-SN' after conversion becoms f1'=m.fS-f1 (provided that I=1-n). Here, (m) is the degree of the high harmonic wave of fS which is nearest to f1-fN. Frequency fS is set as (m-1/2).fS<f1-fN<m.fS or m.fS<f1-fS< (m+1/2).fS. Then, the signals S1'-SN' are taken out by a BPF14, pass through a detection rectifier 15 and a comparator 16, and are outputted by time-sharing by an output terminal 18.
