收音机统调是指高放电路,本振电路,中放电路在接收频率上都能处以谐振状态。统调电路的性能对收音机的整体性能有很大的影响。根据超外差收音机的原理,提出两种统调电路的设计方法,并进行试验,分析试验结果。
Radio tone refers to the high-discharge circuit, the local oscillator circuit, the release circuit in the receiving frequency can be at resonance. The performance of the tuned circuit has a big impact on the overall performance of the radio. According to the principle of superheterodyne radios, two design methods of tuning circuits are proposed, and experiments are carried out to analyze the test results.
