multiple FFT's for 2 sec of sampling

[lfoitek]

hi,
i have an input signal that i am trying to do around 16 separate 1024 point FFT's so i could get around 2 seconds of sampling(8k samples per sec).  there would be two output arrays, one complex and one real. can anyone help me do this and would there be a way to display each of the 1024 FFT in waveform graph? i attached a vi that has a sine wave as an input for simplicity. thank you,

Ifoitek-

It sounds like the VI you are looking for is the FFT Spectrum(Real and Im) VI. It will take your two waveforms and, for each, output the real and imaginary parts. The real and imaginary outputs are jsut waveforms, so you can display them on a graph.
