Abstract: PROBLEM TO BE SOLVED: To provide a ΔΣ AD converter which can obtain a high dynamic range in a state that a sampling frequency of ΔΣ modulation is made to be comparatively low. SOLUTION: A subtractor 18 subtracts a feedback signal from an analog input signal. An integrator 20 integrates an output signal of the subtractor 18. A comparator 22 compares an output signal of the integrator 20 with a predetermined threshold value, and carries out binarization. A counter 24 counts a clock signal of a predetermined frequency, and measures each pulse width of an output signal of the comparator 22. Output data of the counter 24 are thinned by a predetermined sampling rate of a decimation filter 28 through a loop filter 26. Output data of the decimation filter 28 become AD conversion outputs. A PWM circuit 30 outputs an output signal of a predetermined period with a duty according to an output pulse of the loop filter 26, and the PWM signal is inputted to the subtractor 18 as the feedback signal.

Abstract: PROBLEM TO BE SOLVED: To provide a class-D amplifier whose configuration is simplified and further, which is capable of performing more effective noise reduction than the prior art.
SOLUTION: Sound data applied to an input terminal 1 are supplied through a compensation circuit 2 to a PWM circuit 3, from which a PWM signal is output. The PWM signal is converted to an analog signal through a low-pass filter 5, which is delivered to a speaker 6. On the other hand, the input sound data are delayed by a delay circuit 11, and are converted to an analog signal by a digital-to-analog converter DAC 12. The higher frequency components of the data are removed by a filter 13 and output to a differential amplifier 14, and the differential amplifier 14 amplifies a difference between an output of the low-pass filter 5 and an output of the filter 13, which is then supplied to an analog-to-digital converter ADC 15. The ADC 15 converts an output from the differential amplifier 14 to digital data, which are then supplied to the compensation circuit 2. By doing so, a compensation value based on an output from the ADC 15 is added to the following PCM sound data that are applied to the input terminal 1.

Abstract: PROBLEM TO BE SOLVED: To quickly form a visible image on an optical disk without enlarging a circuit size or complicating wiring. SOLUTION: A visible image is formed on an optical disk by using an optical disk recording device for irradiating the optical disk with a laser beam to form the pit of a length regulated by recording data (EFM modulated data). At least a part of the recording data is replaced by visible image forming data, and becomes recording data including the visible image forming data. When the recording data including the visible image forming data is recorded on the optical disk, the visible image forming data is extracted from the recording data, and becomes a gate signal. A visible image is formed by forming a pit regulated by the recording data within the range of the gate signal. COPYRIGHT: (C)2005,JPO&NCIPI
