Abstract: This paper systematically investigates the key parameters of RLC series resonant circuits—including amplitude-frequency characteristics, quality factor(Q value), and passband—by combining Multisim simulation software with the NI myDAQ hardware platform. The accuracy of the theoretical model was validated through virtual and physical experiments. The results demonstrate that Multisim efficiently simulates resonant phenomena, while NI myDAQ provides flexible support for teaching and engineering applications via real-time data acquisition and hardware control. These tools exhibit significant practical value in both educational and engineering contexts.
