FIR 数字滤波器是数字信号处理的经典方法,其设计方法有多种,用 DSP 芯片对 FIR 滤波器进行设计时可以先在 MATLAB 上对 FIR 数字滤波器进行仿真,所产生的滤波器系数可以直接倒入到 DSP 中进行编程,在编程时可以采用 DSP 独特的循环缓冲算法对 FIR 数字滤波器进行设计,这样可以大大减少设计的复杂度,使滤波器的设计快捷、简单。
FIR digital filter digital signal processing is a classic method of designing a variety of ways, the use of DSP chip FIR filter design can be FIR on FIR digital filter simulation, the resulting filter coefficients can be directly Pour into the DSP for programming, the program can use DSP’s unique circular buffer algorithm for FIR digital filter design, which can greatly reduce the complexity of the design, the filter design is quick and easy.
