ECSE 308 Nusaiba Radi Assignment 02 260672575 A. Review questions: 3.9) Define channel capacity. The maximum rate at which data can be transmitted over a given communication path under given conditions. 3.10) What key factors affect channel capacity? 1. Data rate 2. Bandwidth 3. Noise 4. Error rate 4.5) What are some major advantages and disadvantages of microwave transmission? Microwave transmission is able to transmit large quantities of data for relatively low cost and has less attenuation than twisted pair or coaxial cable. However, it is affected by rainfall, and is subject to interference from other microwave transmission. Microwave radio systems do not pass through solid objects, which can be problematic in cities with a lot of tall buildings or mountainous region. 4.10) What is an isotropic antenna? An isotropic antenna, is a point in space that radiates power in all directions equally. The actual radiation pattern for the isotropic antenna is a sphere with the antenna at the center. B. Problems: 3.15) What is the channel capacity for a teleprinter channel with a 300‐Hz bandwidth and a signal‐to‐noise ratio of 3 dB, where the noise is white thermal noise?

    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.
