| Dec 27, 2013 at 2:30 | comment | added | actlee | For checking phase distortion, I used FFT spectrum with magnitude and phase. Set the input signal as somewhat frequency sine signal, I was changing the frequency over the new Nyquist frequency for checking phase distortion. However, I used very low level checking method that just looking the graph..--; Is there a way that check the phase distortion? If I could check it with a specific way, I think it is possible to make a criteria for tolerating phase distortion. Thank you. | |

However, I used IIR filter,,--; without any reason. Is there any recommendation for resampling? I used 15k. Can I set the cut off frequency over 15k Hz? | |
