Multipurpose Modulator
Jeff Rehg & Ken Felix
Advisor: Dr. T. L. Stewart

This project consists of the development of a multipurpose modulator. Two methods of modulation were implemented - single side band (SSB) modulation and quadrature phase shift keying (QPSK). These are implemented using a Texas Instruments 32010 digital signal processor and a PC interface to perform digital signal processing. The primary benefit of this modulator design is its flexibility. Using one set of hardware, many types of modulation schemes may be implemented. Since DSP is used, changing modulation types involves only a change in software. A second feature of this system is its use to implement signal processing techniques that are difficult to accomplish with analog systems. For example, the SSB modulation uses a hilbert transform to generate the modulation, which is very difficult using analog hardware.
