Default Digital Freqency To Analog Frequency

Say we have a DFT of an analog signal. How would one go about figuring out what points of the DFT correspond to what frequency in the analog world. Say we know the sampling period and that the analog signal is bandlimited.

Nevermind, I'm an idiot.



I was thinking BLT with:

analogfreq=alpha*tan(digifreq/2)


But for such a situation as I described, that was completely wrong.
