摘要： PROBLEM TO BE SOLVED: To provide a falling recording apparatus which can record history, only when an impact due to falling has occurred, and can record a history, even when a battery has been detached due to the impact caused by falling.
SOLUTION: The falling recording apparatus includes an acceleration detecting unit 101 for detecting acceleration; a falling state detecting unit 102 for determining whether the apparatus is in a falling state from the acceleration detected by the acceleration detection unit; an impact detecting unit 103 for detecting an impact; a timer unit 104 for measuring the time elapsed from the start of the falling of the apparatus, when the falling state detection unit has detected the falling state; a falling history accumulating unit 106 for accumulating the history of the falling of the apparatus, when the falling state detecting unit has detected the falling state; and a falling history control unit 105 for deleting falling history information last accumulated in the falling history accumulating unit, when an impact is not detected by the impact detecting unit, when the time measured by the timer unit lies within a predetermined time.

摘要： PROBLEM TO BE SOLVED: To provide a signal processor capable of reducing S/N degradation due to intermittently generated burst noise input, optimizing the gain of a gain control amplifier and reducing reception performance degradation, and to provide a signal processing method.
SOLUTION: For the intermittently generated burst noise input, GCA gain control is interrupted in a noise input section, and the execution or interruption of BB demodulation is decided according to the noise input section and a noise input level. Thus, the reception performance degradation due to the gain insufficiency of the gain control amplifier 115 by the noise input is evaded, and the S/N degradation due to the noise input and the S/N degradation due to desired signal omission are optimized.

解决方案：对于间歇产生的突发噪声输入，在噪声输入部分中中断GCA增益控制，BB解调的执行或中断根据噪声输入部分和噪声输入电平决定。 因此，由噪声输入引起的增益控制放大器115的增益不足导致的接收性能下降，并且优化了由于噪声输入引起的S / N劣化和由于期望的信号遗漏引起的S / N劣化。 版权所有（C）2009，JPO＆INPIT
