WitrynaDesign an Nth-order digital or analog filter and return the filter coefficients. Parameters: Nint The order of the filter. Wnarray_like A scalar or length-2 sequence giving the critical frequencies. For digital filters, Wn are in the same units as fs. WitrynaAs a Python exercise let’s filter and shape some pulses. We will use BPSK symbols so that it’s easier to visualize–prior to the pulse-shaping step, BPSK involves transmitting 1’s or -1’s with the “Q” portion equal to zero. With Q equal to zero we can plot the I portion only, and it’s easier to look at. In this simulation we will ...
