A Hardware Approach to Teaching FSK
Abstract
Many communication concepts are difficult for undergraduate students to internalize, but demonstrations and laboratory experiences are quite helpful. This paper describes how we teach the concept of frequency shift keying by using a highly successful combination of theory, demonstrations, lab exercises, and real-time DSP experiences that incorporate M ATLAB and the Texas Instruments C67x digital signal processing starter kit.
1 Introduction
While many communication concepts are difficult for undergraduate students to fully understand, the use of demonstrations and laboratory experiences have been shown to greatly facilitate the learning process.1–7 This paper describes how to teach the digital communication modulation tech- nique of frequency shift keying (FSK) using a highly successful combination of theory, demon- strations, lab exercises, and real-time DSP experiences that incorporate M ATLAB and the Texas Instruments (TI) C67x digital signal processing starter kit (DSK). This approach, when combined with the appropriate test and measurement equipment, provides a superior method of reinforcing communications theory and many of the associated practical, real-world tradeoffs that students often overlook.
Specifically, this paper describes the addition of a frequency shift-keying (FSK) capability to the winDSK6 program.6 FSK is one of the most straight-forward forms of digital communication. Once students understand FSK it is far easier to help them understand more complicated methods of digital modulation.8–10 This FSK capability is incorporated in a new winDSK6 module, called CommFSK, which includes the following features:
• generation of phase continuous and phase discontinuous FSK with adjustable data rate; • control of the modulated signal’s amplitude, center frequency, and frequency deviation; • source data selection from a pattern of alternating 0’s and 1’s, several PN-sequences, random data, all 0’s, all 1’s, ASCII text messages from keyboard, or data from files; • optional built-in or user-defined asynchronous communications protocol; • user defined FIR-based filtering of the resulting FSK signal; and, • full integration into the winDSK6 program.
