how to separate noise and signal
I have a 10 khz square wave signal filled with noise. I need to separate the noise from the signal by using FFT. For a pure 10 khz signal the FFT shows spikes of decreasing magnitude at 10, 30,50,70,.....khz. But the noisy signal shows random spikes of different amplitudes along with the 10 khz spike. Now the question is how I should determine the parameters in order to filter out the noise.
