FFT Filter

[sandy143sri@gmail.com]

Hey guys,

I want  to  FFT my signal and split the FFT into two parts from  a certain frequency.

I implemented it using two filters and  two FFT. but i want toreduce it to a singale FFT and splitting it.  

Please find my solution.

I do not completely understand what you are asking. Do you want to take the FFT of a signal before the filter, then extract certain portions of the transform output?

Your image shows two waveform wires entering two filters. Do those both contain the same signal or two different signals?

What will you do with the FFT outputs?

Give us an idea of the big picture - what is the  source of the signal(s) and what will you be doing with the filtered results?
