摘要
利用信号需求分析结果,选取待处理的规范指标信号,评价算子的计算说明,完成信号质量评价;在此基础上,通过调整传感器偏振信号、计算测量标准具的方式,对可穿戴式设备信号的频率间隔进行调整分析,完成可穿戴式设备信号频率测量方案搭建;相同物理平台上进行实验,与QT方法相比,应用新型信号频率测量方案后,抗电磁干扰免疫水平得到有效提升,检测带宽占比最大值不超过55%。
According to the result of signal demand analysis, the standard index signal to be processed is selected, and the calculation of evaluation operator is made to evaluate the signal quality. On this basis, the frequency interval of the wearable equipment signal is adjusted and analyzed by adjusting the polarization signal of the sensor and calculating the measuring standard device, and the frequency measurement scheme of the wearable device signal is constructed. Compared with QT method, the new signal frequency is applied. After the rate measurement, the immunity level of EMI is improved effectively, and the maximum ratio of detection bandwidth is not more than 55%.
