Display device, is connected with AD73360 chips, virtual value and digital voltage signal for showing digital current signal in real time
Virtual value；
Wherein, module selects sub- equipment to include based on the filtration module that maximum distribution radius selection carries out medium filtering：Maximum point
Cloth radius is bigger, and the filtration module of the progress medium filtering of selection is bigger, and maximum distribution radius is smaller, the carry out intermediate value filter of selection
The filtration module of ripple is smaller；
Wherein, module selects filtration module selective in sub- equipment to include 3 × 3,5 × 5,7 × 7 and 9 × 9；
Wherein, display device is also connected with AD73360 chips, virtual value and numeral electricity for showing digital current signal in real time
