【Abstract】 In analog circuits, AC and DC voltage and current coexist in each branch, which makes it difficult to analyze the working principle of the circuit and discover the function of the circuit. Using the superposition theorem in the circuit theory, the response of DC power supply and signal source excitation is calculated separately. The calculation is simple and convenient, and the concept is clear. Based on the superposition theorem in this paper, the response of three basic amplifying circuits in analog circuits is analyzed and calculated.更多还原
