Homework 2

Date Assigned: Tuesday, January 27, 2004
Date Due: Thursday, January 29, 2004

  1. Reading: Continue studying Chapter 2 on signals and Chapter 3 on linear systems in the Lathi text.

  2. In class, we computed the channel capacity for a telephone line that is used by a dial-up modem. Refer to the Demonstrations and Class Notes link on the course web page for more information and a sample Matlab program.

    Please compute the channel capacity for a typical cable modem that operates over a coaxial cable. Search on the web to determine the bandwidth, B (in Hz), that is used in most systems. Also, use the web to determine typical signal to noise ratio (SNR) values for cable modems.

Thank you and have fun.
