DIGITAL TEST SIGNAL GENERATOR IMPLEMENTED WITH FPGA

Abstract:
In this paper we present a digital generator which produces sine-wave signals with variable frequency. The shape of the signal is stored in memory. The modification of the frequency is achieved by changing the number of samples used to generate a period. The digital circuitry of the generator is implemented using a field programmable gate array (FPGA) and a microcontroller. Experimentally we have generated sine-wave signals with frequencies between 1รท100 kHz and analysed their content in harmonics. Finally we present some possibilities for optimising the generator.
