Study of Power Supply Influence in a Function Generator and Sinusoidal Signal Optimization

The paper presents a developed functional generator and a study of the influence of the supply voltage on the stability of the frequencies generated by it. Based on experimental studies, the systematic and random errors are calculated and the basic error of each frequency range is determined. Two schematic solutions for the conversion of a triangular to a sinusoidal signal are also proposed, and based on a simulation study in the Matlab programming environment, it is clear that the linear point approximation is the better approach for the conversion of a triangular signal into a sinusoidal one, which is also proved by practical implementation.
