FFT

过这个程序，可以更加深入的了解FIR滤波是如何实现的。用AVR单片机 ATMEGA16L实现32阶FIR低通滤波器设计，低通截止频率为200HZ。原始信号经过AD采集后进行FIR运算，处理好的数据通过串口输出。(About this program, a more in-depth understanding of the FIR filter is how to achieve. The 32-order FIR low-pass filter design, low-pass cut-off frequency AVR microcontroller ATMEGA16L 200HZ. The original signal after AD collection, the FIR computation, the output of the processed data through the serial port.)
