摘要 数字电路信号抗干扰技术是确保传输数字信号高质量的基础,通常数字带通滤波器可以产生噪声和干扰信号,但会限制数字信号的传输频带。文章在RLS算法的基础上设计自适应滤波电路,实现低误差、高效的数字信号传输。有效的干扰信号与数字信号在自适应滤波电路中分成两路进到同相加法器与移相器实行运算,成为混合信号并输送至自适应滤波器之后,对信号误差的最小值进行计算,将误差最小的信号输出,对传输数字电路信号期间的干扰进行抑制。 Digital circuit signal anti-interference technology is the basis to ensure the transmission of digital signal high quality,usually digital bandpass filter can produce noise and interference signal,but will limit the transmission frequency band of digital signal.Design the adaptive filter circuit based on the RLS algorithm to realize low error and efficient digital signal transmission.Effective interference signal and digital signal in the adaptive filter circuit into two ways into the same phase adder and phase shift operation,become mixed signal and transmission to the adaptive filter,calculate the minimum value of signal error,the minimum error signal output,during the transmission of digital circuit signal interference suppression.
