    • Abstract
  • In front-end electronics of PET,in order to restrain noise and improve Signal Noise Ratio of sampled data,a passive second order RC filer is designed.We use HSPICE & MATLAB to simulate and analyze the experiment data,and subsequent experiments indicate this filer can improve SNR of signal.Based on this design,the cost of the front-end electronics can be reduced largely,and the quality of images can be improved
