Abstract

The principle of a new electronic tunneling accelerator is introduced and the desired component

the noise and the disturbance of the sensor’s output signals are analyzed in detail. With the LabVIEW virtual instrument development platform

the method of signal analysis and processing is designed. Based on the analysis of the output signals of the electronic tunneling

the related simulative signals have been simulated and processed

thus restraining the noise and deleting the power frequency disturbance. Finally the desired component concealed by the noise has been obtained.
