MODULE 2 ASSIGNMENT 3 4. Telephone systems use a digital encoding scheme called B8ZS (pronounced “bates”), which is a variation on the bipolar-AMI encoding scheme. How does it work? Why is it used? Show an example using the binary string 01101100000000010. 0s. B8ZS is a common method used in the US to avoid the synchronisation problem of long strings of binary 0s.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
