  • $\begingroup$ At the MATLAB prompt, type openExample('signal/PassSignalThruRRCFilterSigExample'). It'll open an example that shows how to pulse shape using raised cosine filter $\endgroup$ Commented Feb 3, 2021 at 12:07
  • $\begingroup$ @Engineer raised cosine filter? Why do I need it? $\endgroup$ Commented Feb 3, 2021 at 12:32

    $\begingroup$ You’d be very helped by reading some digital communications textbook just to get the basics. Every book has a whole section on pulse shaping. This question has also been answered on this very site! $\endgroup$ Commented Feb 3, 2021 at 12:51

  • $\begingroup$ @Engineer Actually, I have the same doubt as OP. What if its a wired communication application and signal is PAM modulated, for example? In this case the transmitter may not implement any specific pulse shaping.To OP: what is your intended application? $\endgroup$ Commented Feb 4, 2021 at 10:40
