Abstract
This paper discusses one of the most popular projects in our real-time DSP course's, demodulating a telephone's caller ID signal. We describe the use of a modified telephone coupler to allow students to access the caller DD signal, then discuss a number of the DSP methods and techniques that are required to successfully demodulate, decode, and display the caller ID information. This project has been exceedingly well received by both our undergraduate and graduate students and represents a DSP-based solution to a real world communications problem that every student has seen in use. This project involves almost every aspect of real-time DSP, but it's scope is such that it can be completed in a reasonable amount of time.
