Hong , The design previous attached screecap fft3.png , this is a spectrometer with 8 input . I have a new design more simple , this is with 4 inputs with 32 channels and the Multiplier in the implementation of fft_wideband_real is 1 , is this correct ? or Have I change to [1 1 1 1 1 1] ?.
In this new Design the paremeters are: In the fft_biplex_real_4x0 the Size of FFT is 2^4 , then the vector of length 4, the Multiplier implementation is [1 1 1 1]. In the FFT internal block the Size of FFT is 2^2 and the Multiplier implemantion is [1 1]. Finally the fft_wideband_real the Size of FFT is 2^6 and Multiplier implementation is 1, is this correct?
