This paper deals with a logarithmic and a linear chirp sine generation on a fix-point FPGA. Basic overview of the logarithmic chirp sine signal and its usage is provided. Then, methods of software signal generation are described and their pros and cons are mentioned. A point-to-point method, which is able to generate both signals mentioned above, is selected for implementation. Its limitations, such as resolution limit, number wrapping and result rounding, are revealed. Moreover, a formula for maximal error caused by fix-point length, signal frequency, sampling frequency and signal parameters is presented. Therefore, the parameters for a maximal error can be calculated, so the implementation can be modified to fulfil a specific application needs. Furthermore, parameters are calculated to fulfil vibration testing criteria according to IEC:60068-2-6, then the method is implemented to a fix-point FPGA and used for a vibration testing.
