description: The subject of the graduate qualification work is âA powerful frequency generator with load impedance control based on the stm32 microcontrollerâ. The given work is devoted to use of DDS technology â direct digital synthesis â to generate signals with different power and frequency. The purposes of the work are to study methods of digital signal synthesis, to investigate the circuitry of the device with using the Stm32 microcontroller and the AD9837 programmable frequency synthesizer from Analog Devices, to find the best way to ensure parameters stability of the synthesized signal. Modern methods for synthesizing a sinusoidal signal and controlling the load impedance were investigated by studying and analyzing the literature about digital signal processing, DDS. A review of technical specifications was also carried out and elements for the implementation of the generator circuit were selected. The main advantages of the technologies under study were shown on the example of real scheme. The result of the graduation work was the consideration and study of the basic principles of a digital generating signal based on DDS. Modern solutions were found to ensure the stability of the parameters of the generated signal. The principles of modern digital signal processing and current control using a variable resistor were described. A review of the features and benefits of 32-bit microcontrollers Stm32 has been done.
