Original Abstract

This paper deals with a logarithmic and a linear chirp sine generation on a fix-point FPGA mainly for vibration testing, nevertheless the generator can be used also in other areas. Basic overview of the logarithmic chirp sine signal is provided. Then, methods of software signal generation are briefly described and their pros and cons are mentioned. A point-to-point method is selected for implementation and its resolution, errors and limitations on fix-point arithmetic are revealed. Our implementation runs on Compact RIO 9067, uses 32-bit fix-point and is able to generate linear and logarithm chirp signal from 10 Hz to 7 kHz with minimal chirp speed 1 oct/min.
