Analyses of threshold choice method on digital signal system
The paper introduces different kinds of threshold choice method to measure the things sizes in charge coupled device data acquisition and process system. They are fixed threshold method, float threshold method, comparative threshold method, differential threshold method and PWM (pulse width modulation) soft control method. By comparing these methods, we summarize their advantages and disadvantages and put forward their different applicable conditions. In addition, the latter two methods will be paid more attention to.
