Abstract

This essay, aims at measuring general track power supply and a local one, manages to apply all-phrase FFT spectrum analysis technology to 25Hz series track circuit receiver. By taking advantage of the phrase invariance character of the APFFT, which provides us with precise phrase difference under asynchronous sampling without adjustment, we greatly increase the efficiency of a MPU-based 25Hz Series track circuit receiver. We also give a simulation under MATLAB to verify the character.
