Many thanks for the assistance. I read Proakis Digital Communications text book and a tutorial on Shannon in ComplextoReal, the bandwidth is equal to the symbol...

Many thanks for your explanation.In the message, it states that the 3dB of BPSK is the symbol rate.I thought that the first null either side of Fc every 1/symbol...

I captured a BPSK waveform at RF on a spectrum analyser. I need to determine the 99% bandwidth. I have a CSV plot. Does anyone knows how to determine 99% BW...

Thank you. I shall look into this. To determine the classical phase noise of PLL from EVM, do you need to know the integration BW.I understand that integration BW...

This is in reference to Python.I also ran the Matlab code. Does it just plot one graph (Fig.1) showing a complex waveform?

I get an error when I run the code in Spyder.divide by zero encountered in log10 psd_dB = 10 * np.log10(psd)

Thank you for the code.I like to get a common understanding. I can see in the last graph that the spectrum have been inverted due to I and Q being reversed so...

I read one of the message that swapping I and Q (like in the case described earlier)effectively spectrally invert the waveform. Swapping I and Q reverses all the...

Many thanks for the explanation. Do I take it the overall waveform would be the same on the spectrum analyser (upconverted signal at f1, image)?For Rx down-conversion,...

Hello
I done some calculations just to prove for myself but the angles calculated are different.
Real=0.5. Imag=0.9
Phase = arctan (0.9/0.5) = 60.9deg
now...
