For a UWB communication system, by using differential characteristic of Herz magnetic dipole antenna, the narrow pulse can be produced from the rise edge of input square-wavesignal.
在UWB通信中，利用赫兹磁偶极子天线的微分特性，由输入方波的上升沿产生窄脉冲。

Pulse width Modulation device is a circuit which can produce squarewavesignal with fixed period and adjustable pulse duration ratio (pulse width).
脉宽调制器是一种能够产生周期固定而占空比(脉宽)可调的方波信号的电路。

The simulation experiments shows that chaotic detection system is very sensitive to squarewavesignal and have strong restrain ability to any colored noise with zero mean.
