I have signals captured from two channels of a measurement system. There is phase and magnitude differences between these two signals.
I want to apply nonlinear smoothing to the magnitude, but the phases should remain the same after the process.
This is what I have done both channels:
- Perform FFT
- calculate magnitude
- calculate phase
- apply nonlinear smoothing to the magnitude
- get real and imaginary part from smoothed magnitude and phase
- perform inverse FFT.
However the resultant signal is not as desired. It appears as a two sided time signal or has some additional signals in the end.
Is there a solution to this problem?
