the program is used to find out the FFT using time in decimation and solves problem of dsp fft ,compared with inbuilt fft and goertzel function , working well given with output also.
Getting to Know the FFT
What is the FFT? FFT = Fast Fourier Transform. The FFT is a faster version of the Discrete
Fourier Transform (DFT). The FFT utilizes some clever algorithms to do the same thing as the
DTF, but in much less time.
