Hi all,
I'm new to DSP. I'm trying to calculate FFT for an ADC. I captured the digital output from the ADC by using a Digital comparator and stored the output code in a file. I need to know how i can use this digital output codes(1's and 0's) to calculate FFT , as FFT needs real and imaginary parts of the sampled signal.

Thanks.
 

Re: FFT for ADC output

Use matlab to do fft on the data stored in the file.

Re: FFT for ADC output

Hi Amr,
I want to implement a FFT analysis in C. So if I want to give the input to the FFT algorithm in which format the data should as ADC output is decimal converted digital codes? How this decimal numbers can be given as an input to the FFT algorithm.
