摘　　要：差分斜率鉴频器因其良好的线性和易用性在调频波解调电路中应用广泛,但在高频电子线路教学中涉及较少。为此通过深入研究差分斜率鉴频器电路,分析了影响其鉴频特性和线性度的若干关键参数,给出了差分斜率鉴频器中频幅转换网络的设计方法,并使用Multisim软件验证了设计方法的合理性和有效性,为“高频电子线路”课程中有关斜率鉴频器的课程实验或项目的设计实施提供支撑。Differential slope discriminator is widely used in FM demodulation circuits due to its good linearity and ease of use,but it is less involved in high-frequency electronic circuit teaching.By conducting in-depth research on the differential slope discriminators,the key parameters that affect the frequency discrimination characteristics and linearity of differential slope discriminators are analyzed,and a design method for frequency-amplitude conversion network of differential slope discriminators is provided.The rationality and effectiveness of the design method are verified by using the Multisim software,providing support for the design and implementation of slope discriminators in High-Frequency Electronic Circuit courses.
