This filter class is capable to do low/high/bandpass and stopband filterings with different filter designs: Butterworth or Chebyshev Type I/II. This project was created as part of a university assignment. 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 ...
