双调谐谐振放大电路理论仿真分析与实验设计
Experiment of the Double Tuned Resonant Amplifier Circuit Based on Theoretical Analysis
摘要
Abstract
In order to meet the teaching needs of high frequency double tuning resonance amplifier circuit that is absent in the communication electronic experiment teaching,the coupling characteristics of capacitor parallel double circuit in high-frequency double tuned amplifier are theoretically deduced and mathematically analyzed,and the two-dimensional and three-dimensional detailed analysis diagrams of the normalized frequency characteristic function of the circuit are given.In the experiment design,the passband of this circuit has two states of continuous and discrete distribution,and the hardware experimental circuit of double tuned amplifier is designed to verify the correctness.Through the experimental circuit,students can thoroughly understand the principle of the high-frequency small signal resonant amplification circuit and master the circuit design method.关键词
