anonymouse - Sep 13 2011
I wrote an AFSK encoder but am unhappy with it. I did the math to find
a sample rate where it would be an integer number of samples based on
the bitrate so the math is easy. I ... FFT Frequency Range [2 Articles]
bashir siddiqui - Sep 2 2011
Hi,
I have one very simple question. I hope some one will clearify my doubts.
The range of frequencies covered in the output record from the FFT is 0 to
1/2 the sample rate ... Useful grad level courses for future Audio DSP engineers [2 Articles]
