Abstract

PURPOSE: To detect the base sound precisely by feeding a binary signal corresponding to the base sound in the time interval approximately equal to the actual sound length regardless of the sound band, or by forming the signal converter so that the maximum value of a signal in the frequency band is made constant.
CONSTITUTION: The retriggerable monostable multivibration RTM1WRTMn are driven by the output signals of pulse sequence from the comparators CMP1WCMPn respectively. An output signal of the pulse width extended according to the continuous time of the output signal of the filter BPF is obtained in the retriggerable monostable multivibrator RTM, it is approximately equal to the actual sound length.
