IPC: G01S3/805
Filed: 1990-10-19
Abstract: PURPOSE:To avoid that a sound receiver arrangement becomes large in scale and to prevent deterioration of a low-frequency characteristic by extracting only differences of a measured phase difference from a reference phase difference between arranged sound receivers which are within an allowable range, and by subjecting them to addition and synthesis with a phase difference between the sound receivers made to be zero. CONSTITUTION:Output signals of sound receivers 11 and 12 which are amplified 21 and 22 are subjected to frequency analyses 31 and 32 respectively, a phase difference  PHIi between input sound waves is detected 71 for each frequency component and compared 72 with a reference phase difference signal  phii and the phase difference PHIi being within a set allowable range is sent to a phase shift circuit 43, while frequency data OMEGAi thereof are sent to selector circuits 51 and 52. The circuit 43 shifts, by the phase difference PHIi the phase of an output of a complex FFT analysis circuit 32 which is determined as being within an allowable range, so as to it be of the same phase with a frequency component of a complex FFT analysis circuit 31, and sends it to the circuit 52. The circuits 51 and 52 select only frequency components corresponding to the data OMEGAi and output them while a phase difference between outputs of the two sound receivers 11 and 12 holding the phase difference in a desired azimuth within an allowable range is made zero. They are subjected to reverse complex FFT respectively, converted 61 and 62 into signals in a time domain and subjected to addition and amplification 75, so as to drive a loudspeaker 76.

Title: Digital video signal transmitting method and receiver used for this method
Inventor: HERITSUTO YOHAN KEESUMAN
IPC: H04B14/04
Filed: 1990-10-23
Abstract: PURPOSE: To obtain inverse quantization amplitude for a decoding video signal element to the pixels of a sub-image by making quantization amplitude equal to the minimum value of a video signal element in a sub-image at the time of inverse quantization. CONSTITUTION: Although the minimum value Umin of a video signal in a sub- image is quantized and also can be allocated to a 1st pixel of a sub-image that is represented by a binary class 00, it does not always need to be a pixel pe (2, 3). The value Umin can be allocated to >=1 samples that are represented by the binary class 00, but the value Umin is not allocated to all of the samples that are represented by the binary class 00. For example, the Umin can be allocated at most to half the samples of all the samples, but it must surely be assigned to at least one among the samples. For all the samples that are represented by a binary class 11, a maximum value Umax is allocated to at least one of the samples at the time of inverse quantization. As a result of this, the inverse quantization amplitude of a sub-image can be acquired.
