【摘要】：电子产品所在电路中出现的各种干扰信号会导致电路中正常信号波形的畸变,从而影响电子产品的正常运行和使用寿命。为了排除干扰信号对电子产品的不良影响,采用形态学小波构造数字滤波算法来滤除电子产品所在电路中的各种干扰信号。大量仿真实验结果表明,该滤波算法对电子产品所在电路中出现的高频连续干扰、随机背景噪声干扰和电磁瞬态干扰都有很好的滤除效果。
[Abstract]:All kinds of interference signals in the circuit in which the electronic products are located will lead to the distortion of the normal signal waveform in the circuit, thus affecting the normal operation and service life of the electronic products. In order to eliminate the adverse effects of interference signals on electronic products, a digital filtering algorithm based on morphological wavelet is used to filter all kinds of interference signals in the circuits in which electronic products are located. A large number of simulation results show that the filter algorithm has a good filtering effect on the high frequency continuous interference, random background noise interference and electromagnetic transient interference in the circuit where the electronic products are located.
