| 摘 要： | 将FIR(有限冲击响应)数字滤波器应用于低频时码接收机中,并利用DSP(digital signal proccssor)芯片TMS320C5402实现了低频时码信号的FIR滤波。实验表明,FIR滤波可以使信号中混杂的较为严重的干扰得到很好的抑制,并且失真较小,有利于实现高性能的定时接收机。

| Abstract: | An FIR(finit impulse response)filter is applied to a low-frequency time-code receiver and the FIR filtering for the low-frqueney time-code receiver is implemented with the DSP(digital signal processor)chip TMS320C5402.The results show that the FIR filter can restrain the relatively serious interference and reduce the distortion for the signal so as to be helpful for completing the high-performance timing receiver. |
