We can take closer look at the signal after the repetition: In case of rectangular window (left plot) have an ugly discontinuity, which can be hardly seen in case of triangle window (right plot). Webb29 okt. 2015 · Our first step in this post is to define a "time" vector, with which we will define the hamming window we want to analyze. In [2]: m = 513 t = np.arange(m) Using this time vector, we can define our window signal w using SciPy's get_window function (found in the scipy.signal module).
