Filed: 1999-10-25
Abstract: PROBLEM TO BE SOLVED: To provide a noise whitening method for stably and optimally detecting a signal against various fluctuation in noise characteristics by means of a simple process. SOLUTION: Spectrum characteristics of noise constituents in a wave receiver signal received by an array type sensor are whitened respectively, and their output signals are analog/digital-converted individually. On the basis of the output signals, beam outputs in a plurality of azimuths are formed, and the frequency of each of the formed beam outputs is analyzed over a predetermined analysis width. On the basis of the analyzed frequency analysis result, the spectrum characteristics of the noise constituents are estimated, and frequency constituents of the respective beams are normalized with the nose constituent spectrum estimated values on the basis of frequency analysis results and the estimated values of the spectrum of the estimated noise constituents. The normalized spectra are added up in the band, and the addition result is outputted to a processing unit.

Title: Level conversion circuit
Inventor: AKATA MASAO
IPC: H03K19/0175
Filed: 1990-11-07
Abstract: PURPOSE:To perform CMOS/ECL level conversion by performing level shifting and by using a diode to prevent the base potential of an output bipolar transistor from becoming too low. CONSTITUTION:When a high level is impressed upon an input terminal VIN, a MOS transistor M2 is turned on and the base charge of a bipolar transistor Q1 is extracted through diodes D1-D4 and the transistor M2. When the base charge is extracted, the base potential of the transistor Q1 is dropped to VSS+4 Vf by means of the diodes D1-D4. Accordingly, the VBE of the transistor is not excessively reverse-biased. When the base charge is extracted and the electric current disappears, diodes D7 and D8 are turned on and suppress the potential drop. Therefore, the occurrence of an excessive reverse-biased state can be evaded and CMOS/ECL level conversion can be performed with small power consumption.

Abstract: PURPOSE:To obtain high energy efficiency and to make a device compact by compensating wavelength dispersion generated among acoustooptic elements of a composite system by a dispersion optical system. CONSTITUTION:The wavelength dispersion generated between an acoustooptic modulator 3 and an acoustooptic deflector 6 is compensated as the whole composite system by one dispersion optical system by arranging a prism 5 between both, and placing the acoustooptic modulator 3 and prism 5 in conjugate relation by an incidence-side relay lens system 41 and the acoustooptic deflector 5 and prism 5 in conjugate relation by a projection-side relay lens system 42.

Filed: 1988-12-02
Abstract: PURPOSE:To trace the execution history of a program in a normal action timing by using a means to output the branch destination address and the branch generating status to the outside of an information processor at occurrence of the program branch. CONSTITUTION:At occurrence of the program branch the branch generating status is inputted to a circuit 7 which outputs the branch destination address and the branch generating status. In such a case, the circuit 7 outputs the branch destination address and the branch generating status to a trace device 3 to record them there. At the same time, the device 3 receives the data on an external bus 10 of an information processor 6 via a monitor signal line 11 and traces the execution history of a program. Thus it is possible to know a specific branching point of the execution history of the program based on the trace data on the device 3 and therefore to estimate the flow of the program. In other words, the output of both the branch destination address and the branch generating status is possible to the device 3 even in the case a cache memory 4 is kept turned on with addition of the circuit 7. Then the flow of the program is estimated.
