Abstract

Digital signal processing techniques are widely used in complex electromagnetic environment. In this paper, digital filtering techniques in PMR are studied to reduce the influence of high frequency interference, noise and burrs on angle measurement. Firstly, the digital filter for PMR is designed instead of the analog filter. Then, the performance and filtering effect of the digital filter is verified by computer simulation. Finally, the digital filter is implemented with TMS320F2812 DSP. The test results shows that the designed digital filter can effectively improve the quality of the received signal and provide condition for high precision angle measurement.
