光电化学是研究在光照影响下的各种电极过程的一门新兴学科。在大多数情况下,光电化学实验体系所产生的光电响应非常微小。假如采用常规的放大方法,其结果微弱的光电响应将和噪声一起被放大,为此必须采用微弱信号检测技术,把淹没在背景噪声中的光电信号检测出来。信号平均技术就是一种在光电化学中常用的微弱信号检测技术。
Photoelectrochemistry is a new discipline that studies various electrode processes under the influence of light. In most cases, the photoelectrochemical response generated by the photoelectrochemical experiment system is very small. If the conventional amplification method, the result of the weak photoelectric response will be amplified together with the noise, for which must be weak signal detection technology, the submerged in the background noise photoelectric signal detected. Signal averaging technique is a weak signal detection technique commonly used in photoelectrochemistry.
