| Abstract: | Mechanical resonance frequency has an obvious influence on theodolite performance. On the basis of traditional double-T net filter, an improved digital filter is proposed in the paper. The filter can control the amplitude of mechanical resonance by adjusting proper parameter. Experiments show that the improved digital filter is better than traditional double-T-net filter. |
