ON PICKING-UP AND PROCESSING METHOD OF MICRO-CURRENT CHEMICAL SIGNALS
摘要
Abstract
The picking-up and processing method of micro-current chemical signal need to combine computer hardware with its software. In hardware, logarithm and antilogarithm converters are used to carry out logarithm current-voltage conversion of the micro-current signal, mean-while the transistors is used to compensate the temperature fluctuation in the converter. This will increase the input signal' s dynamic range and improves the signal-noise ratio comprehensively. In software, the Gaussian low-pass filtering processing is employed. The third power mean value filtering is used to approach Gaussian algorithm for increasing the calculation efficiency of the system, and also effectively filtering the blank noise.关键词
