WebMar 13, 2024 · 可以使用C语言中的FFT库来完成测频，例如FFTW库。. 使用该库可以方便地进行快速傅里叶变换，从而实现测频功能。. 以下是使用FFTW库进行FFT测频的示例代码：. #include #include #include #include . #define N 1024 // 采样点数 #define Fs 1000 // 采样频率. WebMay 17, 2024 · The first thing to note is that the argument to --with-fftw must be the top level path to the FFTW3 header files and libraries. So for example if the headers are in /usr/include and the libraries are under /usr/lib (the default, when package libfftw3-dev is installed from the Ubuntu repository), the value should be given as --with-fftw=/usr

WebIntroduction FFTW is a C subroutine library for computing the discrete Fourier transform (DFT) in one or more dimensions, of arbitrary input size, and of both real and complex data (as well as of even/odd data, i.e. the discrete cosine/sine transforms or DCT/DST). We believe that FFTW, which is free software, should become the FFT library of choice for …
