Impact of digital signal processing on measurement and test instruments

The authors discuss the impact of digital signal processing on test instruments and describe the use of a single-chip digital signal processor called TriStar whose architecture has been tailored for the instrumentation environment. TriStar instructions and programming are described, and attention is given to typical applications of TriStar, including averaging, fast Fourier transform, and interpolations. The authors explain how the processor delivers high throughput for these applications.<
