## Main Question or Discussion Point

I have the readings from a signal in a file (floating point values) that I wish to apply the Fourier Transform to.

The samples (mV) were taken every 4 milliseconds and I wish to transform them into the frequency domain.

How would I apply the FT to a set of values without knowing any function that can describe even a discrete sample of it?

Thank you to anyone who can offer any insight!
