The specterum analysis of double-speed sampling based on LabVIEW

摘要

To reduce the spectrum leakage that comes with signal processing of single-speed sampling, the computer simulation of signal processing has been realized with double-speed sampling by using LabVIEW. According to the specterum analysis of these two sampling method, it show that double-speed sampling method decreases time-bias accumulation of sampling period and spectrum leakage, and gives higher precision than single-speed sampling method.
