    Sir. Again great video. One more question. Around 6:43, u say that the timing between the maximum and the first zero crossing is the symbol rate. How does this apply when the signal is a pulse where the maximim is bascially across a span of time. Would we consider the the initial time when the first maximum occurs?

    Hi Sir. Great video. Around 8:43 u say that one of the problems with the boxcar is that the time domain signal "fall off very slowly." What do you mean by that?

      Sinc signal in time domain spreads infinite over time that means they slowly fade away over time.
      With boxcar in freq domain the equivalent time domain representation is sinc function whose amplitude reduces slowly over time
      But in case if we use pulse shapping filter like raised cosine, it will be easier to separate signals in freq domain as well as we get a sinc like function which fades faster in amplitude and is finite
