Title: Adaptive digital filter and echo canceler using the same
Inventor: SAKAI YOSHIHIRO
IPC: H03H21/00
Filed: 1991-02-19
Abstract: PURPOSE:To prevent deterioration in echo cancellation quantity and unstable operation by preventing an error in coefficient value due to bit discarding from being accumulated. CONSTITUTION:This adaptive digital processor consists of a fixed point digital signal processor which employs complementary notation of '2' and outputs the difference between the dummy sent signal of a 1st input signal and the 2nd input signal generated by passing the 1st input signal through a transmission line 11; and a coefficient is updated so that the output signal becomes minimum, the same characteristic with the impulse response of the transmission line 11 is obtained, and the dummy sent signal is obtained from the 1st signal. Adding means 23 and 24 adds a constant correspond to the bit discarding generated at the time of the update of the coefficient to the 1st input signal. Further, the echo canceler uses the transmission line 11 as an echo path for generating an echo to obtain the output signal after the echo is removed by the adaptive digital filter.

IPC: H04N19/503
Filed: 1997-02-07
Abstract: PROBLEM TO BE SOLVED: To eliminate block shaped noise that is produced when an image whose high frequency component is lost by a high compression rate is decoded in decoding a still image by inverse discrete cosine transformation IDCT. SOLUTION: A block prevention filter used to prevent transposition of a block shaped noise in a moving image technology is adopted so as to check whether or not an edge at a border of blocks is natural in the vertical and horizontal directions and to apply filtering to the edge. In the case of the horizontal direction, for example, mean values of values of pixels P0 -P3 and pixels P4 -P7 are compared and the result indicates an exceeded threshold level, the filtering is applied to one or both of the P0 -P3 and pixels P4 -P7 so that the P0 -P7 are changed smoothly.

Title: Phase shifter
Inventor: MATSUMOTO KEIJI
IPC: H02M1/08
Filed: 1978-03-08
Abstract: PURPOSE: To reduce extremely the dispersion of the phase-shift characteristics with no use of the 2nd variable DC power source by combining the bridge-connected rectifier with the constant voltage diode.  
     CONSTITUTION: Constant voltage diode 3 is connected as perscribed to the output terminal of rectifier 15 in which four units of diode are bridge-connected, and the input terminal is connected to terminals A and C of rectifier 15. Thus, the signals clipped by diode 3 via rectifier 15 is applied to integrator 5 even though power source 1 features the positive or negative cycle. The forward voltage drop is very similar for the diode, so output waveform b of the rectifier is well balanced between positive and negative sides. Thus, a phase shifter can be obtained with an extremely small amount of dispersion of the phase-shift characteristics just by securing a fixed value from the negative waveheight of output waveform c through the positive waveheight with adjustment of the time constant of integrator 5.

Abstract: PURPOSE:To secure an easy real time processing and a high recognition rate by normalizing an average of a frequency characteristic in a timewise equal division voice section in each band of an input voice at every corresponding band and inputting it to a neutral network. CONSTITUTION:Each recognition word calculates a frequency characteristic of a voice through a band pass filter 11. At every band of the filter 11, a waveform is divided equally timewise and each section is set as one block, and an average of the frequency characteristic is calculated by an averaging circuit 12. An average in an (i) block of a (k) band of a sound signal is denoted as Stik and normalized 13 by dividing it by the sum SIGMAi Stick of levels of all blocks in the corresponding band. This value is inputted to a neutral network 20 and from a value of an output layer, an input word is decided by a deciding circuit 30. Since an input parameter is a frequency characteristic, the pre- processing and the arithmetic processing can be executed quickly in parallel, and also, this method is strong against a stationary spectral distortion and a high recognition rate can be maintained.
