数字化滤波器在移频锁相系统中的应用
资料介绍
滤波器是移频锁相系统中的重要组成部分,文章从典型的移频锁相系统出发,提出锁相环电路中带通滤波器和低通滤波器的应用需求,并在成熟的模拟滤波器的基础上,推导出数字滤波器的传递函数,对两种滤波器的幅频和相频特性进行了仿真对比,最后简要介绍了该数字化滤波器的软硬件实现以及仿真测试结果。
Filter is an important part of frequency-move reception system.The application requirement of band-pass filter and low-pass filter in PLL is proposed.And The transfer function of digitalized filter is inferred on the basis of mature simulation filter.The amplitude-frequency characteristic and phase-frequency characteristic are compared through simulation method.Finally the software realization method,the hardware design and the simulation test are introduced.
