Abstract

The ready availability of low-cost high-speed digital signal processor chips has resulted in their widespread use in many areas of industrial and consumer electronics for processes such as filtering, coding, estimation and spectral analysis. This article explores the opportunities of learning about digital signal processing (DSP) using a spreadsheet and a specialized simulation software package, developed by Texas Instruments for their TMS320C25 processor, that mimics the device in terms of its functional capabilities. A finite impulse response (FIR) digital filter is used as a typical example to demonstrate the ideas presented. Application programs can thus be entirely tested in a software environment before being used on a real-time target system
