In electronic information systems, sine waves are widely used as test signals, reference signals, and carrier signals. The most direct method for generating sine signals is to use an operational amplifier with a small number of external components to form a sine wave oscillation circuit. This article uses Multisim virtual simulation software to design and simulate the RC sine wave oscillation circuit. Dynamically reproduce the working process of the oscillation circuit, achieving the process of circuit oscillation and balance. Then, the circuit is improved to further achieve the output of square and triangular waves. Not only can it visually observe the output waveform, but it can also appreciate the influence of circuit parameters on the waveform, further verifying theory through practice, and better achieving the combination of theory and practice.
