Multi-Component or Single-Component: Are there more than one type of signal within your recording multiple tones at multiple frequencies moving in different directions? I posted this question on dsp.

filter

If you are looking at your filtered signal in the time domain, the amplitude will probably decrease, depending on the frequency content of your original signal and the characteristics of your filter.

How to get wrapped phase data from unwrapped phase data

For me, a supper signal with 1000000 samples has the best output.

image processing

Negative gain margins indicate that stability is lost by decreasing the gain, while positive gain margins indicate that stability is lost by increasing the gain.

How can i determine phase in FFT?

For calculating phase spectrum, its result is very noisy because of floating rounding off error, it causes during calculation arctan even small rounding off error produces significant noise in the result of phase spectrum, for suppressing this kind of noise you can define a threshold value.

However, my output isn't exactly correct, so something must be wrong.

An example is given in order to clarify the usage of the function.

Phase angle

You converted some input value to radians according to your comments, so the radius of each polar plot represents radians for something.

If you inspect the frequency spectrum after performing the FFT, you will see, that there are not two clean frequency lines, but a lot of frequency components around two places.

Phase angle

I used fast Fourier transform fft y in MATLAB on the signal and then plot the result of transform versus sample frequency and I thought it's possible to get phase of the signal by angle fft y , so I plotted this on the last graph.
