Abstract:
In them odern techno logy o f electronm easurem en t, all kinds of phy sica l quan tities can be ana lyzed through transduce r by converting them into s igna ls. The process o f amp lify ing and trea ting signa ls in the channe l o f e lec tron m easurem ent w ill be unavo idab ly d isturbed by various no ises wh ich, once added up on usefu l signals, are certa in to lowe r the accuracy and va lidity of the resu lts m easured. Among these no ises, a popular and inevitab le no ise, add itive no ise, is analyzed in the paper through its three form s: therm a l no ise, sho t no ise and cosm ic no ise. Based on this, the paper then puts forw ard the theory of no ise silenc ing in the channe l and proves its feas ibility and rea liza tion in the real e lectric c ircuits. By g iv ing some so lutions to problem s, the pape r ends w ith a conclus ive result in the rea l practice.
