The DFT is primary tool in digital signal processing. So, we will see how it works and how we can implement it within MATLAB and discover its relationship with SNR.
-
First of all I created a sinus Pulse with two frequencies f0 and f1 to test if DFT can detect them or not.
-
Secondly, I added some noise to my original sinus with various values of SNR.
-
In the end I plotted the DFT in Frequency Domain and extract the relationship between the DFT and SNR.
