Analysis of plant electrical signal in the time domain and frequency domain
Lanzhou Wang · Journal of China Institute of Metrology · 2005
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.
