      Agree! I like the idea of the comic stylistic choice for the presentation, but maybe toning it down a little bit would be better.

    Where was generator polynomial used in the process?

    • @wisconline
      @wisconline  8 років тому +3

      The generator polynomial used to create the feedback registers is x^5+x^4+x^2+1. Note though that I do not believe this meets the criteria for a true CRC. I used this very simple polynomial just to illustrate how the feedback registers work when calculating a CRC code. A true CRC would have 16 or 32 registers.

    "there's no delay" -> "let's run this code through the loop again" - Well.. isn't that a delay?

    • @Leonelf0
      @Leonelf0 6 років тому

      Harry Svensson the data is fed through the registers (generating the CRC) as it's sent out to the receiver, then the crc is sent out aswell. the receiver generates a CRC as it's receiving the data and compares it to the received crc. so the only"delay" is the time it takes to receive/send the CRC. calculation is done when sending/receiving

      Your suggested pronunciation may be more popular but it is acceptable either way [sahy-klik, sik-lik] as found here: unabridged.merriam-webster.com/unabridged/cyclic or here: www.thefreedictionary.com/cyclic
      The popular pronunciation of both cyclic and cyclical varies around the world. Sometimes it may sound like cycle or sometimes like bicycle. - Thanks!
