| Abstract: | An A/D, D/A conversion circuit of data acquisition and information process system, used in a small-sized aircraft is described in this paper. ADC,DAC chips of high performance are used. For the complicated electromagnetism condition, new design methods are presented to improve circuit transfer precision and system dependability. In addition, measures are taken to enhance the anti-interference ability in design of PCB. Experiments show that this can meet with the requirements of the system. |
