FFT of DSP c (F2812)

Fast Fourier Transforms are an efficient class of algorithms for the digital computation of the N-point Fourier transform (DFT). In general, their input sequence are assumed to be complex. In many real applications, the data sequences to be processed are real valued. Even though the data is real, complex-valued DFT algorithm can still be used. One simple approach creates a complex sequence from the real sequence; that is, real data for the real components and zeros for the imaginary components, The complex FFT can then be =applied directly. However, this method is not efficient as it consumes 2N memory locations (Real & Imaginary) for N point sequence. When input is purely real, their symmetric properties compute DFT very efficiently. One such optimized real FFT algorithm for 2N-point real data sequence is packing algorithm. The original 2N-point sequence is packed as N-point complex sequence and N -point com
