Abstract: |
In order to improve the test precision and realtime effect of mec
hanical transmission system, the mechanical transmission test system is designe
d based on DSP and allphase FFT. The system consists of the hardware for data
acquisition and processing with DSP and the software with allphase FFT algori
thm for digital signal processing. The experiments have proved that the system h
as such advantage as strong antiinterference ability,high accuracy,and good re
altime effect. |
