Hi Guys,

Im working now on a project related to Noise Test for an Op-AMP. i am to make use of the digitizer which requires me to use FFT commands to digitize the time domain signal of the Noise that i am going to measure. Does anybody know FFT commands that ic an use to see the noise signal on tiem domain? my frequency of interests are 1Khz and 10Hz, i need the commands on C ********. Ideas would be greatly appreciated.
