Abstract

PURPOSE: To obtain binary signals corresponding to plural base sounds simultaneously by providing a signal extraction unit that receives plural binary signals as the input, extracts one or plural fixed binary signals from them simultaneously and emits them.
CONSTITUTION: The input terminals of the filters BPF are connected to the output terminal of the amplifier AMP in parallel. The detectors DET1WDETn detect the envelopes of the output signals of filters BPF1WBPFn. The comparators CMP1W CMPn make the output signals of corresponding detector DET1WDETn binary signals. When a musical sound signal is applied to the input terminal 10, binary signals corresponding to the respective base sounds are sent to the output terminals T1WTn. The signal extraction circuit 30 receives these plural binary signals, extracts one or plural fixed binary signal simultaneously and emits them.
