Re: How can i display the signal out of a FFT block to a graph?

[JFT']

Hi,  For the Y-axis, it depends of the input data binaries.  I mean,
if these come from a voltage signal or a collection of data or a sound
signal, etc.  It's necessary to know the factor conversion the voltage
values, for example...
 And for the X-axis, that represents the axis of frequencies, and its
posible to reconstruct until the nyquist order of the harmonic
frequency (FS/2).Also it's important, the lenght of the input
data, it's a power of 2, since algorithm FFT gives a fast and optimal
result.
  Then connect the output to a Waveform Graph Display, on the front
panel.
I hope this help.
Bye..

Hello St. Augustine,

You should not need to do any conversion from the output of the FFT
VIs to the waveform graph.  Make sure, however, that you are wiring
into a Waveform Graph.vi and not the Waveform Chart.vi.

What conversion is required in order to convert a the output of a FFT
block to a waveform display? The signal input to the FFT block is a
binary pattern signal!
