【摘要】 利用重力场和永磁磁场叠加环境中运行的扇形摆及相应配套电路,制作新型超低频基准脉冲式信号源.该系统运用对复摆的非接触式柔性阻尼调节,使系统输出方波的脉宽、幅值及周期连续可调.其装置既可作为信号源,亦可不经整形直接用作较大功率脉冲电源.更多还原

【Abstract】 An ultra-low frequency reference pulsed signal generator was fabricated by a sector pendulum and a corresponding circuit.The sector pendulum worked in the superimposed environment which could achieve flexibility damped adjustment,by gravity field and permanent magnetic field.The signal generator could output the pulse square wave that could be continuously adjusted in pulse width,amplitude and cycle.Results show that it can be used as the signal source as well as the pulsed power supply.更多还原
