FFT program with text description in Russian

The file contains a fast Fourier transform (FFT) program with weight windows. A signal is generated, then weighed in one of the windows, an FFT is done, and a graph is plotted in the Matlab package. Windows can be easily excluded. The FFT algorithm is implemented completely in an open and understandable form for modernization (not by the built-in Matlab function). This working algorithm is ideal for porting to C ++, Pascal, ASM, Basic languages ​​for graduate or course design. The seller is the author of the program, so he will be able to answer questions.
