Abstract: <P>PROBLEM TO BE SOLVED: To provide a multi-valued logic circuit which can be constituted even without using a normally-on insulating gate type FET and in which the relationship of input and output voltages is not restricted, and a multi-valued specific value logic circuit of which a function is known from a multi-valued logic circuit name given by the present inventor.  <P>SOLUTION: For example, a multi-valued specific value determining circuit of a common embodiment uses a bidirectional switch (connection body of transistors 21, 24 and diodes 10, 12) in which the section between an output side switch terminal and a driving part is turned off in a bidirectional manner during off driving by a first invention. The concept of "specific value" is introduced into a multi-valued logic by a second invention to be limited to a function that "it is decided whether or not the numerical value of an input potential is equal to the numerical value (m) of a specific potential Vm, the specific potential Vm is outputted when they are equal to each other, or an output is opened when not". Thus, the multi-valued logic can be constituted even when it is a normally-off type, eliminates harmful defects (said restriction) in the use of normally-on type FET and can be represented in human words in the second invention.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

Filed: 2004-02-20
Abstract: <P>PROBLEM TO BE SOLVED: To analyze acoustic data and to selectively suppress wind noise while preserving signals without requiring special hardware when the wind noise exists.  <P>SOLUTION: This system includes a method and an apparatus for preserving narrow-band signals in the accoustic data while selectively suppressing the wind noise, and a computer program. Sound from one or more microphones is digitized into binary data. A temporal frequency transformation is applied to the data to produce a series of spectra. The spectra are analyzed to detect the presence of wind noise and narrow-band signals. Wind noise is selectively suppressed while preserving the narrow-band signals. When the narrow-band signal is masked by the wind noise, the signal is interpolated through the times and frequencies. After that, a time series is synthesized from the signal spectral estimate which can be listened to.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
