The task: run a spectral analysis and synthesis of functions using the fast Fourier transform (FFT).

With the spectrum analyzer still clear, but with a spectral synthesis of function - no. Tell me, what is this synthesis, and what is its result? As the clause specified that if you do a reverse FFT, you need to consider 1, 2, 4, 8 ,16 and 128 values obtained using the direct FFT. What it means to take these values into account?
