摘要
在时域和频域上对植物电波信号进行了分析.植物电波信号的幅值处于μV级量级,是一种微弱信号;随时间变化剧烈,在不同时刻的取值关系松散;植物电波信号属于低频信号,其功率谱主要分布在小于5 Hz这一频段.
This article analyzes plant electrical in time domain and frequency domain. It deduced the amplitude value of plant electrical signal was in the μV magnitude, and it was a micro-signal. The plant electrical signal varied acutely with the time and its relativity was weakin different time. The plant electrical signal of was a low-frequency signal, and its power spectrum was mostly distributed in the frequency range less than 5Hz.
