Being new in this:
I have a public domain FFT code in C.
It takes as inputs both real and imaginary parts of the the data.
It also outputs both Re and Im of the spectral result.
In my application I have an amplitude signal vs. time, that is an array of
Volt[t] - the sampled voltage values.
So, is it correct to set the imaginary part of the input to zeros while
the real part is set to the Volts[i] array?
Sorry for the elemental post, but I could not find any code samples that
does FFT on just the real data.
