but it would also be quite easy to create a Gaussian noise waveform if that is what is needed and then pass that through an RRC filter with 50 dB of rejection in the adjacent channel (depending on the proximity of the adjacent channel and roll-off factor used in the filter). The...

To use slice notation with a sequence that supports it, you must include at least one colon in the square brackets that follow the sequence (which actually implement the __getitem__ method of the sequence, according to the Python data model.) Slice notation works like this: sequence[start:s...
The greatest thing about PyCon is the feeling of belonging to a community. That’s only made possible by the great people who give back to the Python community, and you can become one of them! There are lots of ways that you can give back to this great community: ...
In the provided example, we first generate a noisy sine wave usingnumpyand add random noise to simulate real-world data. We then apply the Savitzky-Golay filter to smooth the noisy curve. Thewindow_sizeandorderparameters are tuned based on the characteristics of the data. ...

The added noise is normal Gaussian noise typical of most circuits and is uncorrelated (not related to) the signal. While not strictly true, the model assumes noise is a constant and distortion increases with signal level. This is a reasonable if simplified approximation of...

There is a lot of great articles online that explains the details of word embedding and the algorithm to generate them. So here, I will skip most of them and try to give you a rough idea of what it is. Word embedding is trying to convert a word to a vectorized format and this vecto...
