DIGITAL SIGNAL PROCESSING LABORATORY EXPERIMENTS USING C AND THE TMS320C31 DSK

To perform the experiments, the following tools are needed:1. Texas Instruments’ DSP Starter Kit (DSK), which includes a board withthe TMS320C31 floating-point processor and input and output (I/O) sup-port. The DSK board contains an analog interface circuit (AIC) chip thatprovides for[r]

perature.Books and articles have been published that address the importance of digi-tal signal processors for a number of applications [1–17]. Various technologieshave previously been used for signal processing. The more common applica-tions using DSP processors have been for the audio-frequency ran[r]

capacitors. However, a digital filter, such as a finite impulse response (FIR) fil-ter, operates on discrete-time signals and can be implemented with a digital sig-nal processor such as the TMS320C31. This involves the use of an ADC to cap-ture an external input signal, processing the[r]

This Chapter can be used as a source of experiments, projects, and applications.A wide range of projects have been implemented based on both the floating-point TMS320C30 digital signal processor [1–6], briefly described at the end ofthis chapter, and the fixed-point TMS320C25 [7]. They[r]
