| 摘 要： | 用Keil C开发Atmel公司的AT89C55普通的单片机，设计陷波滤波器，使之在能够满足性能指标要求的情况下很好的运行于低成本硬件，可以达到很好的经济效益。此滤波器可用在医疗设备(如监护仪)对病人状况监视中，对采集的波形信号（如心电、血氧)加以滤波，以得到所需的波形从而进行辅助诊断。

| Abstract: | Using AT89C55 single chip microcomputer by Keil C program, this design develops a trap filter that can work well meeting with demanding parameters in the low hardware that costs consumedly. This filter can be used in filtrating waveform signals (such as ECG) that are collected in medical equipment (such as monitor device) when it make the surveillance to the patient's condition, so as to help the diagnosis. |
