- 频域抽取16点基4 FFT c语言代码
FFT
- 基4的FFT算法程序,它是要通过将长度为N的数据序列转化成大小为4的DFT来实现高速化。从理论上讲,它比执行时间缩短为基2的FFT的3/4。该程序性能优越,可用性很强。下载即可用!

- 选取windows系统自带的ding.wav信号作为分析对象,在Matlab软件平台下,利用函数wavread对音频信号进行采样,记住采样频率和采样点数,听一下原始声音sound(y, fs, bits)。 (2)音频信号的频谱分析,先画出音频信号的时域波形;然后对音频号进行快速傅里叶变换fft(y,N),N取32768,画出信号的频谱特性,加深对频谱特性的理解。 (3)根据频谱,反演时域特性,画出时域波形。寻找幅值最大的两个频率,此频率除以fft点数在乘以采样频率就是信号的主频,即可合
