The frequency modulation receiver includes an automatic frequency controller and a signal detector. The automatic frequency controller receives a demodulated frequency modulation signal demodulated from a radio frequency signal and outputs a control voltage to control an oscillation frequency of a local oscillator. The signal detector coupled to the automatic frequency controller receives the control voltage and determines whether the radio frequency signal is a frequency modulation signal according to the control voltage and a predetermined voltage range."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Frequency modulation receiver and receiving method thereof","description":"A frequency modulation receiver is provided.
